Jason's place was the ideal base for three of us visiting Madrid for MadCool festival. The apartment was easy to get to from the airport and was well-located for getting around the city, with a supermarket a few doors away, and a big park about 10 mins away. The only let down here was the communication. We didn't get any check-in instructions, even after asking for them, so it was a bit unnerving flying to a country without knowing how we were going to get to the place we were staying. Fortunately we did manage to get in after a short wait and phone calls to Jason. I wouldn't let that put you off though. The apartment was large and comfortable. There was a nice balcony, air conditioning in the sitting room and main bedroom, and nice sized kitchen.
