Renzo's house is great! We were parents and two children. The house is comfortable, spacious and very nicely decorated. The rooms are large and comfortable, and the kitchen is fully equipped. All the windows in the house are well protected against insects. The air conditioning works well. The location is also great - quiet but close to shops and restaurants and also to the tram to Venice. Renzo gave us a very detailed overview on everything when we arrived and was available for any question during our stay. One thing that should be improved is the water pressure in the showers (there are two!), which is extremely low.
The bottom line - we absolutely recommend Renzo's appartment!
