Mario met us at the Vapareto stop and walked us a few minutes to the flat. There are no stairs, which was nice. Mario showed us how everything worked and made sure we understood. Limited English, but fine. We enjoyed the windows which opened onto the canal. The flat is very small, but all the windows helped. The bedroom was very dark even in mid-day it was tough to get enough light to see. Some new lighting would work wonders. There are very few places plug in, just be aware. The kitchen was fine, stocked with most everything you'd need and Mario left us some breakfast items. A new coffee maker is needed. The tiny one that was there barely made one cup! We ended up buying instant and using the kettle. There is a great grocery store nearby which Mario pointed out. The prices were a nice surprise, and we bought wine, cheese, bread and salami for perfect dinner / snack, and the cost was virtually nothing.
It's far enough away from the touristy areas, but close enough to walk everywhere within 20-30 minutes. We thought the location was ideal for us. We enjoyed the restaurants in San Giovani square nearby.
The WiFi was nice and worked great for us.
We had some issues with the water heater leaking, and Mario had to come fix it a couple of times so we could shower. He was very responsive, which we appreciated. Mario was really good about responding to anything we contacted him about, and if we needed anything he was there within 15 minutes.
I think we paid more than we should have because we booked it far in advance, a couple of months out and the prices came down a lot. It was our most expensive place we stayed in Italy and the smallest, least favorite place.
It's fine and in a great location. Just manage your expectations and it will be fine.
