My wife and I stayed in Francesca's flat in the Ghetto Nouvo for 6 weeks in Februaury and early March 2020 just as the coronavirus was taking hold of Italy. The flat, which is on the third floor, is in the quiet Cannaregio neighbourhood, andthere are usually a few tourists and tour groups visiting the campo and some noise from the bars along the fondamenta at weekends but nothing problematic. By contrast, the kitchen overlooks a monastry garden and the nuns were also very quiet :-)
The flat is on two floors (three if you count the stairs to the roof terrace - which we didn't use because it wasn't warm enough). The master bedroom is comfortable with an amazing view to the fondamenta and across the rooftops and the Veneto to the snowcapped Dolomiti in the distance. The adjacent bedroom with two single beds has a skylight and a very small window that should not be opened (not sure why). There are two small single beds squeezed into a mezzanine level which would be suitable for children.
The kitchen had all that we needed including a gas hob, oven, dishwasher and washing machine and there are clothes horses to dry clothes (or you can hang them outside the window like a local). The lounge has two sofas and a view over the campo.
The upper floor bathroom has a large shower whereas the lower floor bathroom has a very small one.
We loved the fact that the refuse collectors (i netturbani) ring everyone's doorbell every morning so you can take any rubbish downstairs.
There is some noise from the neighbour's children but again nothing unacceptable.
There's a wide range of interesting bars and restaurants within a few minutes walking distance and the Guglia vaporetto and Alilaguna (for the airport) stop is 2 minutes from the flat. It's a 10 minute walk from the railway station and maybe 15 minutes to the Rialto.
Despite having to flee Venice with a few hour's notice due to an impending lockdown (!), we *thoroughly* enjoyed our stay (partly because there were almost no tourists after the first fortnight) and would recommend the flat to anyone fit enough to walk up 3 flights of stairs and with children used to stairs. Francesca was a friendly hostess and quickly resolved the minor issues/questions that we had.
We felt honoured to have been able to live like locals for a few weeks and we'll certainly be back in the future. Thanks for everything Francesca!
