I was born in Venice. I've been really lucky because I had many opportunities to travel all around the world. Even after all the wonderful cities that I have seen I can still affirm that Venice is really an unique place.
I consider poeple that book an apartment really enviable because unlike most of visitors of this city they stay here for a longer time and have opportunity to feel like a local discovering different routes and off the beaten paths.
For this reason I highly recomend to spend several hours of your time in Venice with an insider.
If you would like to get more info please let me know.
