My wife and I had the pleasure of staying here last week, and it was a perfect experience. The unit was unique, open, and airy, and had all of the amenities (and more) that we could have asked for. You are a 5-to-10 minute walk from anything you need in Old San Juan, from groceries to restaurants to shopping.
As mentioned in other reviews, the terrace was amazing. We were able to sit and enjoy a drink while watching cruise ships and freighters go to and from the port. The views were wonderful, and you are just far enough away from the noise of Old San Juan that it is very quiet and peaceful.
The bed and couches were very comfortable, and the shower had plenty of hot water. All of the toiletries and linens needed were available. We brought our Firestick and linked up with the in-unit wifi, having no problem watching our favorite movies and shows (because of this we can't speak to what is/isn't available in terms of cable, etc.) We did notice that the TV is a Smart TV, so safe to assume you can sign in directly to any of your on-demand services without issue.
Paloma was a dream host. Her responses were quick, and her recommendations for things to see and do were fantastic!
Needless to say, we will be back. Thank you, Paloma!
