The flat itself is nice and matched our expectations (it's a good size, has aircon and wifi, the bed is comfortable, the flat is clean and the location is convenient) but the different issues we encountered (finding dirty cutlery, broken shower fixture, unexpected noise and poor insulation that made it very hard to have a full night sleep, and very little basic supplies - no washing up liquid, no cereal bowls, etc.) made our stay disappointing/quite unpleasant and mean I can't give a better review.
Andrea replied quickly to all my messages and organised to get the cutlery cleaned and the shower fixed but my expectation is that the host checks this ahead of the stay, or offers some kind of compensation if the guests find issues.
Regarding the noise, Andrea suggested to change the fridge setting so the noise in the studio is less loud and and buy earplugs for the noise coming from other flats (doors, taps, etc.) and from the street (the bin lorry comes around 1am so if you are a light sleeper you will definitely need earplugs).
