Overall not bad. But not good either.

It is already 2022, but internet/wifi was unstable. There was no kettle/cups, so it was not possible to drink even tea in the apartment (very inconvenient).
They use some "modern" app instead of keys - however this app is very buggy:
- does not have all the counties in the list to set citizenship (happened in my case),
- registration in app failed THREE times without normal explanation why,
- and this "electronic" key depends on: internet, bluetooth, etc.. and does not support all the phone models... - how it they would handle super-obvious cases when phone accumulator is dead after the whole day of sightseeing in Rome ("rare case", right)? Or how it would work assuming the wifi in apt is unstable? (so lock mechanism would also not function...)
However, personnel is friendly and willing to help. Hope you guys would fix this minor issues! Wish you the best!
