Very nice apartment in great central location, close to the royal palace and Opera. It’s on a relatively quiet street, but right by the Gran Via where it’s more busy. Plenty of restaurants and bars close by, and a few minutes away from malasana and Chueca where there is more than enough choice of restaurants and bars.
The big 3 museums are also walking distance - I believe around 20-30 minutes away.
The apartment has two bathrooms which makes it very comfortable for a group of 2 or 3.
We stayed for a month which went mostly smoothly, but one weekend got unlucky with some noisy neighbors which we could hear partying all night. But I guess thats to be expected in the center of Madrid!
All in all a nice and comfortable apartment in great central location!
