My partner & I stayed for 3 nights with Valentina.
The communication was great both before our trip, ahead of check in and during and Valentina was really helpful in addressing any queries we had.
The accommodation is located in a residential area in Mestre, just over the causeway from Venice. The neighbourhood is quiet but access to Venice is very straightforward via public transport. The tram stop is a short walk away, with trams to Venice running every 10min and taking about 10min to Piazzale Roma.
The room was modern, spacious and comfortable. A lovely touch was the grab and go breakfast and coffee prepared for us ready for the morning. It means you can go out and explore with some fuel to start the day.
Overall we had a comfortable and enjoyable stay at Valentina's, highly recommended.
