We had a great stay at Fernandos place and I highly recommend it to everyone visiting Madrid and looking for a beautiful place in the city centre.
The appartment is really less than 5 minutes from the metro Calloa and the Puerta del Sol. Couldn't imagine a better place
The flat is spacious with enough room for 4 people and looks exactly as shown on the pictures. We found it very clean and it's equipped with everything needed. Fernando was extremely helpful when we weren't able to get the heating on and guided us on how to start it. He is a really great host.
I would definitely stay here again!
