This was my first time in Madrid, and I had an amazing time while there. This was in part due to the very convenient location of the flat, which is located in a nice traditional Spanish neighborhood that is about a 20 minutes walk to the more touristy areas.
Overall, the flat was fine for a short weekend stay, and a good size for two people. However, there appeared to be a drainage issue in the shower, which caused the water to leak pretty badly. The couch in the living area is also pretty uncomfortable, so I would not rely on it if you’re travelling with more than two people.
Despite these issues, the hosts were kind and responsive, and again, Madrid was an amazing experience.
