We had a nice time in Yolanda's flat. She was very welcoming and the communication from was very easy from the start. She provided us with lots of directions and information beforehand so it was easy to find the place. She made our arrival easy and she had even organised cereals, juice, fruits, tea and coffee so we could have breakfast in the place, which was nice. Although I do strongly recommend going for croissants and coffee in a local cafe, there is so much good food in Madrid.
The photos are accurate to what the place looks like. It's small but very clean and functional. It's located in a quiet and residential area south of the city centre. It's very close to the Retiro Park and museums on the Paseo del Prado and it's a 15-20 min walk/3 metro stops to the city centre/old town where it's more lively. The good thing is it's very quiet which is nice if you want to have good nights sleep.
We can recommend Yolanda's place and Madrid is a fantastic city.
