I know nothing about that particular hotel, but will note that I think the location is good. Close enough to the beach and the "action," but far enough that it should be relatively quiet. You're right around the corner from Maxine's, which is not the best restaurant in Miami Beach, but certainly enjoyable enough, especially as they are open 24 hours a day (I think), have a good breakfast menu, and, if the weather cooperates, have nice outdoor seating. Another good casual spot is 27 Restaurant & Bar, which is a 15-minute walk. Of course Lincoln Road is the main drag, which is very close to you as well.

It's also worth noting that some of the hotels on the beach side of Collins Ave. will not object if you use their pool during the day. (I would recommend a don't-ask-don't-tell strategy. If there is no signage indicating that the pool area is for hotel guests only, go for it!) Just beware that if you use the gate from these pool areas to get to the beach, you may not be able to come back through the pool area unless you have a room key from that particular hotel to unlock the gate. (Not a big deal; just means that you need to use the public access ways.)
