We loved our stay at OSR. We were right in the center of Old San Juan, and the space was very spacious and spotlessly clean. The porch is gargantuan, offering beautiful views of both the ocean and the city. The beds were super comfy, and having a washer and dryer was a lovely added bonus. We never had hot—or even warm—water, but we didn’t mind, as it was actually refreshing on a hot day. We love this place and will definitely be back.
