Great location to visit much of the landmarks of Madrid. Check-in was smooth, though having some basic knowledge of Spanish goes a long way. It’s a bit too easy to flood the bathroom floor, due to the lack of a shower curtain.
The main gripe, however, was the construction work going on outside the terrace overnight. Not sure what schedule they work on, but the incessant pounding made it rather difficult to get some decent sleep. It’s probably out of the control of this apartment complex, but it’s something to take note of at the time of this writing.
Other than that, would recommend!
