Adela was very communicative before our arrival and flexible. We wound up adding a day at the beginning of our stay. We were given keys and could come and go. We came in one night at 4:30 am without complaint. Bathroom is shared but good shower. There is no A/C but it was not a problem in Madrid in late June. But the window was open and the noise of the city might disturb some. We came in late both nights and fell right to sleep without issue but if you are a light sleeper, know what you’re signing up for. I think it was a good value.
