Federico is exceptionally professional, friendly, and thoughtful. Listing is spare but clean and cozy; it definitely gets the job done, and it's nice to have a kitchen. The location is great: in just 15-20 minutes on foot, you're in the very center, which was perfect for my research trip to the archives. There are also a number of bars, restaurants, and markets around the apartment. My only complaint was that the wifi, which was not a traditional router, went out for half our visit (especially frustrating since the apartment gets almost no cell phone or data reception); Federico said he plans to replace this something more up-to-date.
