I am going to review the property manager West Indies rentals and the San Cristobal studio separate.
West Indies rentals - I would recommend anyone to book with them. Communication was spot on from booking till checkout. I even had questions before booking and they were happy to answer them. Very clear instructions on check-in and check-out. They even allowed me to checkin couple hours early. Had couple of issues with the room and they were taken care of within a day.
San Cristobal studio - Never again. Room was clean, very good view and having laundry inside the studio was a really good thing. Problem is the balcony especially considering the awesome view you get. It's one of the smallest in the entire building to begin with and on top of that it has 2 AC units with literally 2 feet x 2 feet of space for you to stand. With 2 AC units running non-stop, it becomes so hot to stand in that small space. I tried turning off AC completely, but the second unit belongs to another room.
In general the area felt calm and safe. Photos are wrong though, the mall is almost abandoned now with only 3 stores or so. 15 mins walking to Condado area with tons of restaurants. Parking on that mall was easy and bit cheaper when compared to Hilton's parking. $19 for over 7hrs when compared to $25 in Hilton. Easy access in and out of highways.
I would definitely book with West Indies rentals again, but definitely not San Cristobal studio. They have several other good studios in that building.
