We had a fantastic time in Madrid and at Borja's place. The appartment was super clean and tidy. Borja was always quick to reply via message. Unfortunatly there was a mis understanding with our check in time but Ada (Borja's assistant) was very helpful and was still able to meet us for a late check in. There was a fee involved for this however so please be aware. We had difficulty sleeping the nights we stayed there as there was a Fiesta (hundreds of people partying) happing on the exact same street until late at night/early morning. This however is not Borja's fault, we would have booked elsewhere if we had known though. Overall I would highly recommend Borja's place (just not during the Fiesta period). The location is perfect as you are fairly central to most things.
