We loved our 10 days in the apartment. it is within minutes walk to the metro and Atoche train station. There is a wonderful fresh food market a short walk up the road and the local tapas bars are great for sitting and enjoying the local atmosphere.
the apartment itself was very clean and all the amenities worked perfectly, including WiFi and a variety of streaming services on the TV.
There was some street level noise, particularly at night when the bins were being taken in but I would not complain about this as it meant the area around the apartment was always clean with no trash littering the streets. Dan, the host, was excellent if we needed anything or had any questions.
We would absolutely recommend this apartment and hope to stay again next time we are in Madrid.
