There are three Marriott chain hotels in Condado, this one used to be my favorite, but now is not any more .. at least until the finish renewal work (I understand it is in process of becoming Autograph Collection)
On the pros side: it does get a slightly wider part of the beach. Rooms are ample, with beds often facing the sea view and bathrooms generally renewed. The gym is better than average and overall service is good and friendly. The old breakfast place is good and well located.
However, endless renewal work has left one of two towers entirely unavailable. On the available tower (ocean front), 1 out of 3 elevators doesn't usually work. Rooms have become more noisy because of the very loud music in the hotel's party venues (2) as well as in the neighboring park, particularly in the latter part of the week. The worst, last time I stayed, was the humidity in the rooms .. first room was really unbreathable. I changed to another that already had a loud, bulky humidifier in, which at least did work, capturing half a gallon of water per day!
Lastly, in spite of some fantastic employees (Rafael, Sarai and others come to mind .. always outstanding in every sense) others have gone downhill, like Juan Pablo at the reception who now seems constantly under stress and unhelpful.
Last tip - don't accept Ocean tower rooms finished on 16 or 17 .. those are too close to the elevators and are significantly smaller.
