Nice apartment for a short stay in Madrid. The apartment is in a central location in walking distance to many attractions, restaurants, and bars. I found the apartment very clean and well equipped with everything that I needed. There is enough space for 1-2 people. The only downside is that the apartment is on the ground floor with only a window to a small courtyard, which makes the whole apartment seem quite dark. I think the price is also relatively high for this area of Madrid.
Overall, the apartment and location itself I definitely would recommend if you are mainly sightseeing and not spending too much time in the apartment.
