I stayed at Francisco's flat for a month. The positives are the location, the existence of the a/c (a unit in the living room and one in the bedroom), and the internet (I worked from here for a month and was able to do video calls and all other normal work without issue). Other than that, I did not enjoy the stay. I'll list out what I wish I would have known before making this booking. I did not find the flat clean at all. It had been swept, but very clearly not mopped in ages as evidenced by my extremely dirty socks. The bed was so uncomfortable that I could not sleep it in more than a few nights and ended up sleeping on the couch the rest of my stay (which also was very uncomfortable, but slightly better), and I am in my 30s without any back problems or major injuries, I can't imagine anyone with those would be able to sleep here. It feels like there is no privacy whatsoever, the only "curtains" are on the two windows in the bedroom that overlook the busy street. They are in quotes because they are not actual curtains and do not even fully cover the lower part of the window, much less the whole thing; they are also not attached but just held by the window being closed so if you open it they fall off. I found the bathroom to be quite gross- there is a shower curtain that sort of covers the window, and water can easily get into the odd space next to the window. One time I used the shower head to rinse out the shower and large pieces of black stuff came off and into the tub (see others' mention of mold). I didn't think the dishes or the other kitchen items were clean so I just bought disposable plates/cups instead and didn't use any items in the kitchen except the counter space. I bought my own broom to use while I was there. I do not expect an airbnb to be filled with new things at all, but something like the old dirty sponge should just be thrown away if it's not going to be replaced. A lot of items (ex. dishes, sponge, broom, hair dryer) were technically present, but not in a state that I thought was useable. Due to being on the top of the building with all the seagulls there is an exceptional amount of dust, debris, feathers, etc. that come in so I swept each day (that may not necessarily be something the host can control). The seagulls are extremely loud and the street off the bedroom is noisy -again, something that may not easily be controlled by the host- what can be controlled is the fact that air comes through the windows even when they are closed (this certainly adds to the noise level), as in it was windy outside and the "curtains" in the bedroom were moving. I understand that part of the location means there will likely be noise, but the air coming through the windows seems a bit egregious. There is a lot of space, but I would have gladly traded the space for something that was clean.
I met Francisco briefly and my communication with him was good and he seems pleasant so no issues with him as a person.
