There are definitely some good things about this apartment. There's plenty of space and it's close to a metro (it does take about 7-10 min just to cross all the streets, though) and there's a mercadona supermarket on the same block. There are big windows with lots of light and gorgeous jacaranda trees outside (and even a bird's nest!!). There was almost no noise from the neighbors, and it felt very private and safe.
However, there were just so many problems. The apartment was super dirty when I arrived. I probably spent about 4-5 hours cleaning. Everything was really gross - dead bugs in the shower, every glass/ dish was dirty, and the fridge had the most disgusting smell that I never was able to get rid of, even after a month. I also had to pester the host for 5 days just to get enough sheets/ pillowcases/ towels.
The main problem, though, is that the apartment is on the 2nd floor (3rd floor for Americans), and all of the windows are right at a very busy stoplight at one of the busiest intersections in Valencia. There's super loud traffic noise literally 24/7 (and I'm from NYC, I can tolerate a lot of traffic noise!). There's only one AC in the living room, at the literal farthest point from the main bed, so it's super hot in the bedroom without the windows open. And with the windows open, the noise is impossible, but the ceiling fan does help a little. I ended up sleeping (very poorly) on the couch for most of the month, but there's a really powerful street light right outside the living room window, and that huge window over the sink has no curtain or persiana blind at all, so it was like daylight in the living room all night long.
The bathroom does smell super bad, as is pretty common in VLC, and I did see some enormous cockroaches (again, I'm from NYC, I've seen a lot of roaches, but these were HUGE). The kitchen only has the bare basics, and all of the furniture is very low quality and not very comfortable at all.
