Been here! I came back to England to visit my friends but they happened to be off on a trip and so the day before I bought a super cheap flight with them and slept on the floor of the villa they booked - a lads weekend in Venice was hardly the romantic idea I had in mind when it came to Italy lol... But it was fun. Certainly not claustrophobic - I loved the winding secret alleyways, it's where we found a mega-cheap local winery.

It's so much nicer when you find your way outside the tourist spots
