We did not have a good experience with Claudia. We had booked 4 days but left after 2.
On our first day of arrival, she did not show up although she had said she would be there in evening. This led to a misunderstanding on the rooms to use. Then on second day, she arrive late in evening (we were out) without prior notice. When we arrive as well, she was on the phone with TV on (adult movie playing). Although she must have obviously noticed our misunderstanding, she left us waiting for 1/2 hr and then did nothing to alleviate the discomfort.
We took the decision to leave as this was a very uncomfortable situation. Despite her promise, she did not pay us the nights we didn't stay back (even not partially, as of course, there are AirB&B fees she cannot claim back).
On top, we didn't receive any valuable info on Madrid. We only received a touristic map available anywhere in the city.
