It was great to stay at Federico's place in Madrid. Good location 5 minutes from bus&tube, very quiet neighborhood and a nice little balcony where to rest after spending the day visiting the city.
Federico is the ideal host: polite, always available to help and continuosly communicating with us to ensure the best experience possible. He gave us great advice on nearby places (tapas, traditional sweets) and also on the city (restaurants and directions).
The apartment is not huge but is tidy and has everything you need. We were four people and we had a great time. Definitely looking forward to come back! Gracias Federico!
