Clean place, the staff was very helpful. Outside looks a little outdated but once you go inside it’s perfect! Highly recommended staying here if you’re going to be on the go a lot, thank you all from the staff there!

We stayed here for 5 days during our trip to Puerto Rico and had a great overall experience. Check-in was easy, the property was very clean, and the AC worked really well. We didn’t encounter any bugs, and having parking right in front of the apartment (we stayed in Apt 2) was a huge plus. I did see reviews about street noise, but coming from New York, it didn’t bother us. If you’re sensitive to noise, it’s something to consider. The backyard is a nice shared space with individual hammocks, though it doesn’t offer much privacy. The only downside was the bed — it was a bit too firm for our liking. Overall, we’d definitely recommend this place and would stay here again!
