Javier's apartment is in one of the buzziest, most fun barrios of Madrid, and is within easy walking distance of all the best spots! It is also really clean, very nicely decorated and super comfortable: there were three of us, and both the bed and the sofa bed were perfect.
Javier also has a great television (with Apple TV and Netflix), which was great for a rainy afternoon after a pretty heavy night of partying...
Our only issue was with the fact the air conditioning is centralised and only comes on in June: it was 36 degrees when we stayed in May, and the apartment was very hot for sleeping (and very loud with the windows open). Javier was very kind and provided an electric fan, but it was no match for the Madrid temperatures!
Javier is a fantastic host: he stayed up for us when our flight was really delayed and welcomed us to the apartment personally. He was also on-hand to give us great tips on where to go, and went the extra mile to ensure our stay was brilliant - thank you very much Javier! We would certainly come again :-)
