We stayed in the room with the balcony- it is a stunning room with lovely views! The room is very spacious with a table and private bathroom. The balcony is not for sitting out on but 2 of us were able to stand outside, although a tight squeeze. At night the balcony does mean passing by gandolas and early bin men on boat, this did not bother us too much as we were usually awake anyway. I personally found the bed very uncomfortable, lumpy and hard but everyones preference is different. The location is great, easy walk to local restaurants and attractions. We had good communication through emails but did occur a few problems. One of which seems to be on airbnb; the address seems incorrect but their own website is spot on and the second was about our breakfast. The person emailing us did not let Gianni know about our celiac request. But Gianni soon sorted this out the following day. Just to warn you tea lovers- there is a great selection of fruit tea and coffee but no 'normal' tea so make sure you bring a bag of English breakfast tea if you crave it! On arrival Gianni greeted us warmly, gave us a map with directions to local attractions, supermarkets and restaurants.
Overall it was a beautiful stay and with all of my research very good value for money with a balcony!
