A Perfect Stay on Ocean Drive I had a wonderful stay at this hotel right on Ocean Drive in South Beach. The location is unbeatable—just steps from the beach and in the heart of all the action. The customer service was attentive and friendly, always ready to help with a smile. The on-site restaurant was a pleasant surprise—great food, good vibes, and drinks. The decor throughout the hotel is stylish and inviting, with that classic South Beach charm. Highly recommend for anyone looking to soak up the Miami vibe in comfort and style!

The property had just gone under new management, and things were a bit hectic. Unfortunately, we didn’t have TV service during our entire stay. However, the manager, Eric, went above and beyond to make up for the inconvenience—providing $15 food vouchers throughout our visit and waiving the resort fees. What a fantastic way to turn things around and keep a guest happy! Superb team and a perfect location. Be sure to go see Eric and his staff—they’re truly amazing individuals!

"Nice quiet stay. Pools were nice. Beach is advertised but not really usable for swimming, snorkeling, etc. The bathtub faucet didn’t work and our air conditioner wasn’t functioning properly - it was always 75-76 degrees inside, which made for uncomfortable sleep. We were told maintenance would come, ..."

"This is a fairly clean place. It has a great location to the water with jet ski rental at the property. The only real issue is the rooms are extremely noisy. We could here every step of the occupants above us and the highway noise was very loud in the room."
