Great location - we were able to walk pretty much everywhere the hop on/hop off goes. Right in the middle of Central Madrid and the old section. Apartment very functional and comfortable, well decorated. Actually pretty cozy. . The bedrooms are very dark, great on days of early sunrises if you want to sleep a little later. The only negative is the walls are paper thin and from the bedrooms you can hear pretty much everything happening in the other apartment so I presume the opposite is true. Although we could hear the neighbours tv at night, it wasn't obnoxiously loud and were able to fall asleep in spite of it as there was no conversation (we presumed the person lived alone or was a single airbnb user)
