We had a great time at xxxx's place. Our contact was with Catarina, a lovely lady that welcomed us and all the logistics went smoothly. Regarding the locality, it was a pleasant surprise staying in Giudecca (note that we had the week vaporeto ticket).
The house itself was a perfect fit for my family and I (2 young my children) and additionally it is very well equipped for cooking. The view is amazing and has big windows that allowed us to spent lovely evenings there. We highly recommend it ! Grazie mille.
