It was an absolute pleasure staying with Gonzalo in his stylish apartment in Madrid. There is everything you could look for in an Airbnb - the apartment is full of amenities so you don't have to go and shop around, The location is also very central so great for tourists alike and in terms of security, the place is a simple lock-up and go.
Highly recommended and would definitely stay again on a return to Madrid. Many thanks again, Gonzalo!
