We had a great experience at Carlos' flat! He was very helpful in providing detailed information a week before our stay, regarding our commute to and from the airport, how to collect the keys, connecting to wifi, parking rules, etc. The apartment was neat and comfortable, and the staff at the desk were friendly and helpful. It is a bit far from the center of the city, but close to two metro stations and the airport, which made it convenient for us. Overall, I recommend this flat and Carlos as a host!
