Have stayed there twice.
POSITIVES:
1) LOCATION -can't get any better, just around the corner from Nana Plaza, and stones throw away from Check In Bar and Chaos 9/Paradise.
2) PRICE - dirt cheap
3) CLEAN - acceptable cleanliness level.
4) BREAKFAST - it's okay, nothing special, and very small table area.
5) STAFF - I've found reception staff to be very pleasant. Security guard at door ? Don't wake him.
6) ACCESS TO MAJESTIC GRANDE'S POOL AND WORKOUT ROOM - it's a short walk down the block.
NEGATIVES:
1) SMALL ROOMS - claustrophobic or matchbox would be accurate terms. For that reason, the only two times I stayed here was during my virgin trip to LOS, and another time when I was arriving at 11:30pm or so and leaving the next morning at 8:30am (business).
Otherwise, spend a few extra bucks and stay at Dynasty Grande on Sukumvit Soi 6 or one of the other BM-recommended hotels on here.
