Arnaldo was a clear, quick, and friendly communicator. The flat was in a great neighbourhood - not just central and well-connected, but charming in its own right.
Immaculately clean with a smart bathroom. It is a little loud at night and there’s a little bit of a bad smell (we guessed from the drains), but this smell is also on the Metro and in other parts of Madrid, so not unique to the flat!
There is also no storage for clothes but this didn’t matter too much, we only had 3 outfits or so for a short stay.
There’s not a lot of natural light but that was also fine, as we really only used the flat as a base to sleep in, as we were out all day exploring Madrid!
Would definitely recommend for a short stay :)
