Don’t be alarmed by the 4€ fee collected for city tax… it’s a legit fee that all of the hosts in Venice have a right to collect… just have a little cash on hand. I don’t know if it’s per night or per stay… I only stayed one night.
The train station is next door- literally- noise free with the window closed. Take the train in or out- it’s only two stops, for 1.40€. The bus 7E works as well, but you will have to make sure to pick the right stop and walk less than 5 minutes.
If you want to stay in Venice and not really worry about the noise, darkness, humidity or cold- this is a great location. It’s in the middle of the international district, so I’d you want some really good Chinese food- this is a great place. It’s on a Main Street- with the cross street also lined with shops and eateries.
I didn’t explore because I didn’t knew the house rules- the host communicates using VOIP and translate- I didn’t want to keep her up either. So if want a place to sleep for a night- good sleep.
