My stay at Carlos flat in Madrid was simply amazing. The flat is in a quiet and good neighborhood, close to all needed amenities, and has good connections to all parts of the city. Moreover, the flat is very cozy, quiet and tastefully decorated. Carlos is a wonderful host and his family treated me just like a family member. Every morning, Carlos brewed delicious coffee for me, and he helped me above and beyond with seemingly endless acts of kindness. I highly recommend his apartment.
