The apartment is located in a very nice area close to metro and 5-10 minutes walk from city center.
For 2 people it’s perfect place to stay for couple of days. Be ready if you want to make some breakfast - you should buy everything including salt/sugar. But, the good thing-there are many different supermarkets around. If you are not a breakfast person - you have plenty cafes in the area.
One more - if you are sensitive to noise-be prepared to hear all neighbours. Despite the required silence time after certain time, some people were not keeping it. But, it’s not critical if you are exhausted enough after intense day in Madrid (and there’s plenty activities to do, believe me).
Raul was extremely helpful with all the details about check in and general information.
