My husband and I spent a two nights in Venice at Euginio's. Euginio was a great host and he has clearly been doing this for a while. The directions were perfect and the check in was smooth. the room was small but had everything you could need including an aircon and was sparkling clean. The shower area was a bit small but i think that's typical across Italy. My husband is over 6" and had a tough time fitting in there but it was manageable for a couple of days. We were a bit apprehensive since this was the first time we had opted for a private room through Airbnb but Euginio made it absolutely comfortable. We had our own set of keys and the room and bathroom are in their own little corner next to the main door making it very private. Euginio had everything prepared for us including recommendations and maps.
The best thing about the place is the location. It is right in the middle of the old Town and everything you want to see is a 5-15 minute walk. Overall, it's a great place if you want to be right in the middle of the action and just need a clean, comfy place to come back to at night.
