We chose TheBetsy for our stay at South Beach based on the fact it is a member of the SLH (small luxury hotels) group. We have stayed at a few of these around the world and have always been impressed with the decor, ambiance and service. They must have very strict criteria for hotels to become a member, because they are all great!
We were not disappointed, our 5 night stay was divine. We were upgraded to a suite, so had plenty of room to spread out. The restaurant, BLT was excellent, great service, delicious food. Expensive unless you select their 4 course special, and then it becomes quite cheap relative to other restaurants in South Beach.
Location is right at the end of all the Art Dec buildings, but its classier than the rest. Definitely a cut above the rest. Staff were all helpful and friendly. Highly recommended!
