We stayed at The Residences only for a couple of days and its location was very central, close to Salamanca and all its bars and restaurants. It is also close to the jetty for the ferry to go to Mona, so really ideal location.
The apartment was clean and tidy and very secure.
We had some issues taking our luggage up to the 3rd floor, but we weren't travelling too light.
We didn't meet Diana, but she was very nice and gave us all the details that we needed to checkin
