(1,464 reviews) We love, love, love the 1 hotel in Miami. The facilities are immaculate, the staff are accommodating and friendly, we’ve always had a gorgeous room when we’ve been there. We had a very small issue with our showerhead- my husband reached out to the concierge and it was fixed immediately while we were at dinner. I had a great, very relaxing prenatal massage and enjoyed meals at all of the restaurants on the premises. If you’re in Miami and want to be on the beach in the lap of luxury, go to 1 hotel!
