We enjoyed staying at Gemma's place. It's located in a neighborhood with lots of restaurants and shops and it's very close to El Retiro park, which is amazing. The apartment is small but has everything one might need, including a washer. Gemma also left us tea, chocolates, and a bottle of water. For Madrid, the apartment was pretty quiet as it doesn't face the street (and it's also at the end of a hallway so there wasn't much noise from within the building). On the other hand, since the apartment faces a small inner courtyard there isn't much natural light. The apartment was pretty clean when we arrived, but it didn't seem like it had been vacuumed as we found lots of hair on the ground throughout. Additionally, the sheets were clean, but the cover had a couple of spots. Still, the kitchen, bathroom, towels, etc were all clean and I recommend Gemma's apartment.
