I spent a week with my sister in Madrid and it was amazing!
Sandy was always very helpful. If we had any questions, Sandy responded very quickly.
The apartment is very well located, in the heart of the city. We never used the metro and walked to all three museums (which are located quite close and can be reached within 10 minutes from the apartment). Next to the apartment, there are a lot of nice bars, restaurants, shops, there is a nice bakery (Brown bakery with fresh bread), pharmacy, supermarket and even Starbucks (everything is just next to the apartment). The shopping mile is also only a 10 min walk away from the apartment.
We were very happy, thx again Sandy for your warm welcome and that we could stay at your place!
As already written by others, you can hear the neighbors, but by 12 pm. everything was quiet. Also the floor was for us a little bit cold, but we brought slippers with us, so it was fine.
We would definitely recommend Sandy's apartment!
