We were three students and we spend 3 nights in Cristina's apartment. It was a really nice stay, Cristina provided us with everything we needed (towels, map of the city) and the apartment was as pictured in Airbnb, simple and great. Her dog is lovely. The location of the apartment is amazing, near the Metro line and the bus (n°87) which was really helpful. It's a little bit noisy at night but it's ok as long as you aren't focusing on it.
