The place is a little attic that used to be a storage room and has been reconverted into an apartment. It is small but comfortable and matches the description. Heat and shower work well. The bed is ok, although it doesn’t have a mattress. The access is a bit uncomfortable, specially if you are traveling with luggage, because there is an old elevator that does not reach the highest floor.
The worst part was the check out. We stayed for one night and check in wasn’t possible until 3PM. However, the next day Alejandro wasn’t flexible with check out, which is at 10AM. It is true that it is indicated in the description but we hadn’t paid attention because we are used to check outs at 11 or 12, specially with a late check in at 3PM. However, we were required to leave at 10 and find a locker room for our luggage somewhere else.
