Trip was great...would have eliminated the Paris leg as I have been there too many times now.
Venice was really cool, like no other place I have ever been. Like the lack of noise from vehicles. Easy to get away from crowds. Walking Venice at night is the best.
We visited Murano and Burano and purchased our own chandelier.
Barcelona is truly a great city. No sign of the financial wows plaguing the rest of the country. It has everything and very live-able.
Did the airbnb and vbro for accommodations since we were four. Would do it again as our locations in all three cities were second to none and averaged $200/nt.
