Base Hostel is a very nice hostel and the location is really strategic! I will definitely stay there if I visit San Juan. The only thing that I am concerned about is the quiet hours. I think it should be reinforced. When I was there, there were a group of girls came back around 4am and they were talking very loud. I had to ask them to keep quiet so that everyone could sleep. But overall, the stay at Base Hostel was great!
