Victor has been a super host with good recommendations. He for example recommended us Cardamomo Flamenco theatre which was a great experience or Raimunda restaurant where the food itself wasn‘t quite of our taste but the atmosphere was really beautiful!
The apartment was really the best. We felt at home from the first minute. We stayed for a week and had more than enough cupboards to store all our clothes and stuff. The apartment had already most stuff of the daily need like detergent, soap, toilet paper but also salt, sugar, oil, vinegar etc.
Additionally the A/C was really nice - super silent, worked really good and was much much needed in Madrid in July. We had smart TVs in the living room and bedroom and were able to relax and watch netflix, disney+ etc in the evenings.
Only thing I have to point at is that the upper part of the maisonette is only accessable over a really steep stair and the upper part (includes second bath and second bedroom) has a super low ceiling I could only have stayed there on my knees. We never went up there but it was no problem as we didn‘t need it as we were 2 people but if you should go to the apartment with more than 2 keep that in mind.
