The apartment is large and in great shape. The room had two beds and was great for me and the friend I was traveling with. The location is indeed excellent since it's in the centro historico, which works well for both sightseeing and access to public transit. There are cool bars and restaurants just outside. My only complaint is that you could hear the loud music from the bars until the early hours, but i was tired enough that I was still able to sleep. The place definitely felt safe, if that's a concern. Karla was very welcoming and made me and my pal feel at home. I would stay there again.
