My partner and I stayed in Nadia Bettega's apartment for a little more than a week. It was perfect. Nadia emailed me a bunch of recommendations before my arrival (for local grocery stores, restaurants, and sights), and she gave us a lot of practical advice about getting around the city. She's a charming and generous host. The apartment itself is beautiful and comfortable: we made constant use of her terrace and well-equipped kitchen. The neighborhood feels like a neighborhood, not like a special zone for tourists (some parts of the city felt that way), and it's easy to get almost anywhere from there. If I ever get a chance to return to London, I hope Nadia is still renting her extra bedroom!
