Second time I stay here. If you get a discounted rate it's a great value for money, especially if you're an independent traveler and already know your way around BKK. The location on Google is accurate, as is the shortcut to the MRT location.
The rooms are large (about 19 sq. mt, not including the terrace), with a great AC, and clean. The bathrooms are nice with great hot water pressure. The wifi is spotty though, and as mentioned several times before, no elevator (if you have heavy suitcases, ask for a room on the second floor). Note that they do keep a strict 1:30pm-2pm check in time. The staff are helpful and accommodating.
One clear negative this time was that in the opposite room on the 5th floor there was a family with a screaming baby/toddler. And I mean the screeching screaming kind, every 10 minutes. I could actually hear it from the 3rd floor going up the stairs. I guess the hotel might have been the only one that would accept them as guests.
