We stayed at Martina's lovely place(s) for 3 nights. After a slightly tough time finding the place (Doh, I forgot to write down the address!), we finally made it to the place, but Martina wasn't there! It turned out she had a family emergency she had to attend to and she made her way back to the apartment within an hour or so. Once she arrived, she informed us that our place wasn't ready, but there was a nearby apartment for us to stay at for one evening instead.
I have to say that we were quite tired from the flight (from USA), but she did an admirable job of handling my grumpy wife and I as we finally got settled in to a place. Once all of that was out of the way, the temporary apartment was great and we were able to get some much needed rest.
We moved to the room we originally booked the next day and settled in there just fine.
Everything was as described, including the WiFi which was extremely important to us. It was extraordinarily cold weather in Venice during our visit, and though the heater did a good job taking the edge off, it was still a little bit chilly for us. The location is also great--slightly away from the main tourist areas, yet close enough to everything important.

Martina is a very warm and capable host and also supplied us with excellent recommendations for places to eat and get drinks nearby. I would definitely recommend staying here.
