The apartment itself is really nice. Although it's small (suitable for at most 2 people) and has very low ceilings, it's well designed, well equipped and comfortable. Of course the location is perfect.
However, Alex was an unhelpful and unresponsive host. Every message I got on Airbnb was clearly automated so I started to think Alex might be a robot. :) This system is fine unless something goes wrong. I was without internet for two days before I finally managed to raise Alex on whatsapp who "fixed" it by letting me access another apartment's router.
One automated message stated "If you've noticed anything that isn't quite right... Let us know." So I told him about the annoying (and wasteful) dripping tap, the fact that there's no bath mat of any kind so the bathroom floor kept getting wet, and several other issues. I received no response. I might have thought he had some kind of emergency and maybe is normally a good host, but I noticed that the fan still makes a terrible noise which someone else complained about 3 years ago!
All in all, as long as you don't need to contact the host for everything, it's a nice enough place to stay.
