Alf was a wonderful host. I arrived later than expected and he waited until I arrived to give me a key and a tour of the apartment. Alf was always available to answer my questions about the apartment and/or the city. The apartment was comfortable and roomy, and the surrounding area felt safe enough to walk around at night and go to the surrounding restaurants and shops (the heart of Zona Rosa). Overall this was a really pleasant stay. I highly recommend it.
