Alvaro's flat is a stunner. The photos do not do it justice. It is in a fantastic location, near cafés and restaurants, the awesome Forestal park, and Mercado Central (go to the empanada place!). Alvaro was a gracious host, even though we did not meet in person, he was always responsive. The building porters are really nice and helpful. If you have the windows open, you are right on a main road, so it can get loud. I live in a city, so it was fine for me. It's an old building and has quirks, so do be aware. I loved it.
