It was a very nice stay. The apartment is very central and was very clean. Rocío also allowed us a late checkout since we had a late flight back home. Really appreciate.
I wouldn't take the apartment if you are more than 4, otherwise it could be a bit crowded. Also in one room was very bright because of the stairway's light fell into the window (which you couldn't turn off). There was a curtain indeed, but it didn't help a lot, a dark heavy curtain would make the room way darker.
Anyhow I'd still recommend using the apartment. Thanks for the nice stay Rocío.
