Xavier's flat is a great option for a stay in Madrid. It's quite central, next to El Retiro, a great park next to the most well known museums of the city.
The communication with Xavier went really well, getting responses very quickly.
Xavier was extremely helpfull and even allowed us to do a late check out, which was great, considering we had a late flight.
On a next trip to Madrid, I'll definitely check Xavier's place is available.
Thanks for everything Xavier!
