My husband and I stayed at the Essex House Hotel for 4 nights. It was in a great location - just around the corner from the South Beach bars and restaurants, a two minute walk to the beach and a five minute walk to some great shops.
This is a very busy spot but the Essex House Hotel is a bit more quiet compared to the beach facing hotels. If you prefer to get away from the noise then this is perfect.
The hotel staff were very friendly and helpful. The rooms were clean and modern. The only downside is that the bathrooms are very small and there is a lack of storage. There was only one small wardrobe and no drawers. Not a problem if it's a short visit.
We would recommend this hotel and would use it again if we were to return.
