Jose's apartment was a fantastic find, situated in a great neighbourhood in Madrid that is central to everything. Despite Jose living in London, he was easy to communicate with and was available to respond to any questions we had. The apartment is an old building, but his appliances and decor are modern and it really was lovely. There was 6 of us, 2 children and 2 adults over 65, and we all managed the 80-stair climb a few times each day (although it was admittedly a tough haul with luggage). I would strongly recommend this apartment if you don't have mobility problems.
