Great apartment, great location, and great host! I stayed for 3+ months and it was a good decision. The apartment had high ceilings and big windows, so there is a lot of natural light and it felt very spacious. The apartment is close to a lot of great restaurants, and near 3 metro stations on different lines, so getting around the city from this location is very easy. It's also walkable to the city center (~20 minutes) if you prefer to do that.
The only negative experience I had was that the neighbors in the apartment above can be loud at times. Alessandra was effective in dealing with them, so that should not be a big concern when considering this rental - but pack some earplugs just in case!
