I traveled with my parents and sister. We had a very pleasant stay, the apartment was clean, well heated (we were there in January), perfect for 4 people, very well situated, just 4 minutes' walk from Reina Sofia Museum. A metro station is very near (5min walk), local supermarkets just outside the building, a lot of bars, bodegas and restaurants too (no noise in the apartment though). Hans was a great host, gave us tips about the most popular attractions and prompt responses when we asked for anything. 👍👍👍
