Although we didn't take advantage of it enough the hotel served breakfast every morning. Front desk staff awesome and very accommodating. A few times we had minor issues in our room and front desk staff would have maintenance up to our room in a matter of minutes. Minor drawback. A lot of hotel staff seemed not to know how to speak english well but front desk would let maintenance know the exact problem we were having and when they would arrive to our room we didnt need to talk that much because front desk already gave them the run down. I think hotel is in the best section of south beach. Beach 1 block away and walgreens across the street.

Our room was excellent and we had beach and ocean front view with wraparound balcony. The master bath was enormous with jets in the tub and a large standup shower. The guest bathroom was ok as weak with just a standup shower. My only complaint is that we were really high on the 21st floor and it’s very windy up there.
