Livia and her husband are very great. The train came early around 11am but we could still check-in, just needed to write message to Livia in advance. The location is great, if you arrive at Fienze SMN station, take bus 11 and walk around 3 mins to reach the house.
The room is clean, with provided towers, and everything you need (wardrobe, small desk, TV, mini-fridge), and of course, air-con for the hot summer. The bathroom is spacious and fully equiped.
We couldn't make time to meet Livia but her husband welcomed us warmly, gave us some advices for the dining and cafeteria.
I recommended this host
