Carlo was a great host and I had a very pleasant stay at his flat. The room is ideally situated in a very quiet street, at the heart of the city (perfect if you plan to visit Madrid!). The flat is really clean and tidy and the room is quite big and bright, with a very comfortable bed. Carlo was super nice to me, very accommodating with my last minute booking, and he gave me good tips to get started in the city. Gracias/Grazie/Merci Carlo!
