Very well located studio (3 minutes from Reina Sofia, 10 from the Prado) very close to the old city centre yet far enough not to be surrounded by tourists when you get home. The apartment has a Carrefour City located just up the street, a very nice and authentic food market with great tapas, wine, a vegetarian restaurant with local dishes, and other local food.
It is generally a nice, comfortable, well decorated studio. It terms of cleanliness, the kitchen, bathroom, towels and bed-sheets were all impeccable (and comfortable – shower worked very well, nice towels, ultra clean sink).
The apartment had soap, shampoo, coffee, tea and other small things which were pleasant little extras to find.
Marta was kind, discreet and a flexible host (in terms of our arrival and departure time she adapted to our needs perfectly). She even equipped us with a pair of umbrellas during our stay.
In conclusion: a well-located, well-equipped, cosy and comfortable apartment to stay and visit Madrid.
