I was with my husband in Miami for a conference, and the Raleigh is perfectly located just 2 blocks from the Conference Center. Close enough to run back for lunch and mojito breaks between sessions.
Everything on South Beach is expensive (some of it is even worth it), so your best bet is to find a place with great service. When I think of great service, I want genuinely friendly, professional staff. Staff that is obviously more concerned with guests enjoying their stay than in simply earning a tip. The Raleigh did not disappoint. Staff were extremely accommodating (had balloons & cake waiting in our room for my husband's birthday, even when we didn't arrive until the middle of the night). The beach staff (David & Trey) were always anticipating what we needed before we asked, without "hovering" when we wanted to relax. The front desk staff (Tiffany & E. especially stand out), were genuinely kind and professional.
The pool and oasis area of the Raleigh property is truly worth a stay. When you are tired of sunning by the pool, move over to an oasis cabana and relax while reading your book. It was really perfect, my most relaxing experience while in Miami. We are not into the party and clubbing scene, but obviously all of that is close at hand on South Beach. Despite the proximity of parties, the rooms were quiet and very comfortable (perfect AC/fan combo), and stylishly sparse (HUGE walk in closet and spacious bathroom with amazing water pressure!)
Would definitely recommend the Raleigh to anyone staying on South Beach!
