My wife and I booked Fernando's apartment for 5 days. One conclusion we can definitely make is that Fernando is the best host and we don't think we'd meet any host like him! He always made sure we were safe wherever we go and had enough water & food while sightseeing. Every morning and night, he prepares new water bottles for us + breakfast every morning! Before we start the day, he sits down with us and go through every detail on transportation or routes and things we can do in order to make our trip an eventful one. Every night, Fernando checks with us our experience and loves seeing our photos of the day! He made us Sangria and even prepared dinner on one of the nights that we came back late. On the day we left, Fernando woke up at 6am,prepared breakfast for us and walked us to the train station and helped us with our luggage. He stayed till our train arrived to ensure that we took the right one. His apartment is clean and comfortable! The apartment is located within walking distance to most of Madrid's touristy spots. He gave us loads of souvenirs. We are grateful to have met him.
Highly recommended!!
