Oyster
Star Service
Oyster "The hotel has a small fitness center with an adjacent dry sauna, a business center, two restaurants, and a bar -- a nice touch in a neighborhood that tends to shut down by mid-evening"
Star Service "Guests can use the newly updated fitness center, sweat in the sauna or jog through the neighboring botanical gardens"
