My partner and I stayed in early August.
Pros: hosts were super communicative and hospitable from the start. I can't fault the service at all.
Cons: the air conditioner has a humming/buzzing noise at random while it's running. And sadly this noise continues long after the device has been switched off too. This meant it was impossible to use at night as the buzzing was so much it would snap us out of our sleep. And it isnt a rhythmic pattern you can predict, but quite random. On the worst night we'd switched it off before 10.30pm and the last buzzing sound was after 4am, many hours later. We've now seen other reviews mention this so are a bit disappointed the host doesn't seem to have acted on it yet.
We also were surprised that the listing didn't mention that the apartment is directly opposite a bar. There was loud live music or karaoke two of the four nights we stayed, and as the streets there are very narrow, it feels like you're pretty much there even with windows closed. The noise really does impact you when you've had a tiring day or travel or activities and want to rest or sleep. Even after the bar closes at 11pm people linger around for longer talking.
The other major thing is bin collection, which we appreciate isn't the fault of the hosts but something people need to be aware of ahead of booking. It sounded like large waste containers were being dragged across the cobbles for quite some time after midnight, on our last night. It's not just the noise but the vibration you feel too. I'd say it was about a full hour later, after 1am, when we were woken up again by the lorries actually making the collection. This does impact the quality of your stay, unfortunately.
