Jason was very kind and helpfull, we had an almost instant answer to our messages and we liked the fact that he received us at a time of the day when some other hosts wouldn't usually do it.
The flat was tidy, clean and equipped with everything we needed.
Having the A/C was a great plus being that It was very hot at the time we were in Madrid.
The location is great, very centric, well connected and the heart of Malasaña neighbourhood which has a great atmostphere, specially at night.
