The Mondrain blew us away on first impressions, everything is very elegant, from the lobby, to the elevators, to the guest rooms. There are alot of chandlers, even in your shower, and stylish white furniture.
We were very pleased with our room, it was beautifully decorated, quite spacious and had a fantastic view of the pool.
Be aware that there is a charge to access wifi from rooms, but it is free in the lobby and by the pool (which is a great place to hang out!! The pool area is FANTASTIC, it looks exactly like its pictures! There is also a bar and you can order form the reasonable roomservice menu as well). The hotel does a good continental breakfast as well but does not do dinner, but there a few restaurants a short walk away, like Oliver's Bistro. It is also a bit of a walk to the beach, 15-20 minutes I think, which doesn't sound far but in the Miami heat it can seem a lot further!
The service here was great, the staff are mostly very attentive and genuinely friendly which we found very pleasant as Miami, and Florida in general, does not seem to have the same high level of customer service as the west coast of America. We would definitely stay here again!
