Let's start with the slightly negative stuff:

Upon our arrival, I called Charo who then buzzed us in and told us to come up to the second floor. There my brother and I were left wondering whether we actually were in the right place, as nobody opened either of the two doors on the floor. Instead, for a good 5 minutes we had to stand there and listen to a man and a woman shouting at each other in one of the flats while their dog was barking really loudly. Finally, I called Charo again. She and her husband turned out to be the fighting couple.

We didn't get any recommendations from her, and the breakfast she provided us with were tiny buns wrapped in plastic, some stale biscuits and toast.

The doors in the flat are quite creaky, so the first time I tried to shut it, it made a bit of noise. I am a very careful person who doesn't use excessive force, so it really wasn't all that loud. Charo's husband then told me in a very aggravated manner not to slam the door, which I didn't. We apologised anyway and didn't really think about the incident anymore. But a few hours later, I got a message on AIRBNB from Charo, saying that 'they would not indulge such behaviour' and if we 'came to their house to make our stay more economical than a hotel, the least they ask is education'. We felt very attacked, especially since we'd apologised beforehand.

On quite a few photos that have now been removed, a spacious living room was to be seen. We were led to believe that this room was accessible to the guests, which it wasn't.

But we stayed at the apartment for 4 days, and for the rest of our holiday, Charo's husband was nothing but nice. We didn't get to see much of Charo herself.

The flat is easy to find, there is a supermarket in the same street, and you really can explore Madrid on foot if you stay there.

Overall, our stay was very nice.
