The apartment is quaint, but designed nicely. It is close to everywhere you'd want to be in Madrid - which is fantastic.

It's a sufficient space for 1-2 people sleep and shower in, however I was not aware that it was on the 5th floor of a walkup building, which was pretty intense considering my wife and I had been traveling for a while with fairly large suitcases (we're not backpackers). Also there is zero circulation when it's warm outside. There are two windows, but they face a wall so there is no breeze and no AC, only two fans. EXTREMELY warm evenings.

While I never personally met Fernando he was very communicative throughout the whole process, which I appreciate. We met his cleaning service upon arrival - very nice ladies and the place was spotless when we got the keys.
