This place was SO welcoming, SO comfortable, SO convenient, and SO affordable. If I go back to Bangkok, I'm staying here again.
I arrived at about 1 am, and the staffed reception desk even called the airport with my room number so they could deliver my delayed luggage (delivered to me without a hitch). She was friendly enough to talk with me about living in California for 10 years and asking me about Texas.
Everything I needed, and everything was clean, every day. I had a little trouble figuring out how to make the shower water hot, but there was hot water in the faucets, so this was operator incompetence.
I stayed more than a week. I see some reviews said "breakfast not great", but it was great enough for me. I had a business breakfast at the Marriott buffet around the corner, that was ridiculously large, but I couldn't eat that every day. And there were a HUGE variety of restaurants within 10 minutes walk - Thai, Indian, Swiss, German, tacos, pretty much anything you wanted, and they were good and inexpensive.
This place is in an alley that seemed spooky at two AM, but the next day I realized that multiple hotels down the alley had security guards watching me every step.
My only thing to do differently next time will be to take the Sky Train back to the airport - cabs in traffic were expensive and took at least three times as long.
I could say more, but if you're in the area, just go there.
