Grande Centre Point Hotel Terminal 21

Getting to the hotel by taxi can be a bit roundabout, but the location is incredibly convenient, right next to the MRT Sukhumvit Station and BTS Asok Station if you turn right out of the hotel. There's an escalator in the lobby that leads directly to the second floor entrance of Terminal 21 mall (it's usually open until 1 AM). The hotel boasts excellent, free-to-use sports facilities; the tennis court requires a reservation (you can borrow rackets, but tennis balls need to be purchased, though they aren't expensive). The swimming pool is also fantastic! The in-room facilities are a bit less impressive. The soundproofing is decent, but there's a slightly stale smell upon entering the room, likely due to older air conditioning ducts, and the AC unit can be a bit noisy.
