Don’t hesitate, book this place! It’s steps away from everything you will want to see/experience in Madrid. We didn’t take the metro once! It’s within walking distance to everything.
As for Danielle’s place, it was clean and fully equipped with fresh towels and bed linens. His friend, Aran was the one to check us in as Danielle was away for the weekend and we didn’t have any problems. Aran was helpful and communication was good. We will definitely be back the next time we come to Madrid!
