Did you ask them why it says 400B on the website and they quoted you 500B madwolf..?

when they quoted 500, I said "on your website youlist the standard-room at 400", but then the lady again replied the price is 500 and nothing less. so why should I as a potential guest start any fruitless discussions WHY the price is not same promoted ? its not my business WHY the price is different. what counts for me as a customer is , that the information I was given online, proved to be wrong.
but anyway, dont wanna start a big argueing over that. They will know what they do and so do I.

the price does change with the location of room, 1st 2nd 3rd floor, cheaper as you go up. also, on some holidays there is a surcharge, which i cancelled that time. but nice place to stay if not needed to be in farang catering area. very quite.

I've stayed at the Jan Condotel a few weeks last year and a few weeks the year before. First time was a bit over 400 baht per day the second time maybe 450 baht.

The staff doesn't have English skills and aren't likely to explain their rent options. Mostly Thais stay there and I suspect most of these Thais are teachers working at the nearby schools.

The big disadvantage IMO is that it is a ten minute ride to the Robinson shopping mall or the Irish Clock street. The very good Thai open-air eatery, Oyster Hot Pot, is around the corner on Phosri Road. I don't like the Oyster Hot Pot dish, but the rice dishes are wonderful. Everything Good Restaurant is a ten minute walk away. If you don't have a laptop, two inexpensive internet shops are across the road. Snack shops across the street. Many shops in walking distance.

disadvantage IMO is that it is a ten minute ride to the Robinson shopping

that is an advantage to me, prefer quiet area, close to nong prajack, as you say, enough food in the area. may have to try that oyster pot, tho oysters aren't my thing.

January 27th quoted for monthly stay:-
"Rate room for 1 month 10000 bath not include electricity,water.
Rate room for 2 month 7500 bath not include electricity,water."
Free clean your room once week.
Adding on electricity,water costs is something I'm not used to and would worry me!

Jepp, there's reason to be worried but this is not an uncommon practice in condos. The problem is, if the cost of electric is (for instance) 5 baht per watt/hour at the source, the condos may charge you 7-10 baht per watt/hour on your bill. Had this happen to me when I rented a condo in Jomtien in 05. They are likely to take the same advantages of their customers on the water.

Pak is correct it happening to me were I rent my electric bill is much higher than it would be if
I was billed by the company directly as well as my water bill but all in all I am comfortable were I live and that the most important issue

As Paka says this is not an uncommon practice even in hotels in Udon if you are staying long term.
Your choice - you can have an all in room rate, or a rate (considerably lower) excluding water & electric (&, in certain places excluding things like fridge & TV - you provide your own).
For example, when I was staying at the Top Mansion I was paying something like 9,800 a month "all in". A friend of mine was paying 3,500 but supplied his own TV & fridge & paid for water & electric separately.
Ignoring the initial capital costs the most expensive recurring item in running the room is electricity to run the A/C. Guests will often run 24/7 as they are not paying anymore if they do. Hence this option, it is win/win as long as you are frugal with the A/C & depending on the rate they are charging for electric.
There will be a meter attached to the room (well 2, 1 water, 1 electric). As long as you ascertain what they are charging per unit (& Paka has given you good advice above) then you can read the meter yourself & ensure all is 'above ground'.

tip, before renting room, look at room you will rent, trip the room breaker, and make sure the meter has stopped spinning, as if spinning, you may be paying for hall or outside lighting.

when looking for an apartment, was quoted various rates as mentioned. if owning your meter at house, ttl unit price is rarely over 4 baht, so based on that, 5-7 would be fair add on, above that or on the way to 10 or more baht, and suggest you move on. water should be less than 100-200 baht a month, never more. we use 26000 liter at house, family of 3, lots of waste, 375 baht max.

then the is the hassle, possible scam of getting deposit back, if only for one month, i personal would avoid all that and simply go all inclusive rate, clean room and piece of mind. at time, top mansion was 4000 pay as you go, or 8000 all inclusive, figured the electric would add 2000 anyway, and without any other knowledge would just go all inclusive. no matter what you decide, negotiate a stay that you pay for one week, if stay the full month, it reverts to monthly rate, this way after a week, if decide not for you, you are not stuck there, as a friend had found out at one place and lost the rest of prepayment, and decided to rent elsewhere anyway.
