The location is perfect! You can walk to many big tourist attractions and the street downstairs has LOTS of great food spots (we ate at Taberna Descubierta 4 or 5 times!)
As other reviews have mentioned, the bed is actually two twin beds pushed together and is not very comfortable.
The apartment itself is as described, but was missing small things like laundry detergent for the wash machine and a cloth for drying dishes. But these are small things and overall the apartment was great!
