The apartment is in a very good location close to Gran Via station as well as bars in every direction even one in the building itself. If your looking for space this is not for you but the location will make up for it. It’s comfortable for 3 people max as there is not much room to move around once the sofa bed is open. Then again I’d imagine you’re only there to rest, sleep and not entertain so it would be ok.
The bar downstairs is pretty cool and highly recommended as well as the ramen restaurant a few doors down.
If ever you do laundry take note that there is no drying rack. Maybe this can be provided when people are staying longer.
Otherwise a cosy place good for our travel to Madrid.
