Casa Las Ruinas is a great option in Old San Juan. The property has oodles of character. The location is phenomenal. The units are spacious and well-maintained. The property managers communicate clearly and regularly. It's a managed apartment set-up, not a full-service hotel, so some of the fringe amenities one would reasonably expect from a full-service hotel are absent, including an onsite front desk, porters to help carry luggage to rooms, etc. But that should be clear from the way the property is presented online--which is to say honestly. On balance, though, what one gives up on these fronts one makes make in other ways, including price, which I certainly found to be quite reasonable given what one gets for one's money. Bottom line: I would certainly consider staying here again the next time I find myself in San Juan.
