The team and management with Cavalier hotel was phenomenal! They went above and beyond to ensure I was comfortable and enjoy my stay. The airline lost my luggage and they had a ton of problem solving recommendations as well as making sure to notify me as soon as my bag arrived. Not only did they have it ready for me, but helped me bring it to my room! I’m sure there are fancier places to stay, but I will be coming back here for the hospitality!

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.

What I like about our stay the Riu Miami Beach was that the entire staff of the hotel was friendly, accommodating, helpful and went out of their way for the people staying at their hotel. The hotel was very clean as was our room, and had all the amenities you would want and like.

Great beach. Service did not match the service charge nor the disappointment of the staff that wanted a tip in addition to the service charge and all related add on fees.

Stayed here for 5 nights - they charged a daily resort fee but closed off the pool at 2 PM on NYE for their private event. If you went to the beach they make you go through a long detour through another hotel in order to get back, with lack of clear signage or staff to redirect the traffic, horrible. The maid service on NYE was horrible, didn't provide us with fresh towels or replenish the shampoo/conditiner/body wash. The price you are paying does not justify for the quality of service you are receiving.

Most impressive is the access to beautiful beach. However the rooms are a little outdated and the added amenities costs such as but not limited to umbrella each day $25, parking $49 a day, $44 facility fee per day, anything extra cost and gratuity added as well as beach employees charging fees and services we did not get was an issue. A lot of kids and family oriented but very small pool considering we were unable to use pool due to it being way too crowded. The second best thing was the Ocean Restaurant service, food and convenience was excellent. Would come back for beach access and food.
