Studio 154 is absolutely beautiful and the location can't be beat!
When booking, avoid interior rooms (try to book a waterfront room with deck) as they don't have any windows, the club on the floor below plays loud music until @3am, and the smoke comes up through the vents. We had these issues plus a hole in the ceiling of our room (it rained so water dripping on our heads was no bueno!). We contacted our host and they took care of us immediately, offering us a different room and a later checkout. Also, they offer a private car ride to/from the airport which was very convenient and the driver, Tony, was nice.
This is a hotel, so you can either book on their site directly or through AirBNB. I didn't get a clear answer from our host as to whether or not we paid a premium booking through AirBNB.
One other thing to note - the rooftop deck is not open until they receive proper permits, which was not communicated to us when booking. If this is of interest to you, ask the host before booking.
All in all, they are going through typical growing pains (they just opened 5 months ago) but are handling issues with grace and speed.
