Mimi was extremely helpful since before we landed in Venice. We (I, my parents and 2 friends) had a very pleasant stay for 4 days - everything about the house felt just like home. The cleanings supplies were provided in plenty; there was an extra cooler just for the kitchen - that was very thoughtful given the hot and humid weather at the time.
The location was spot on. We did not have to even buy the city pass as every place we needed to go within Venice (except of course the distant islands of Burano and Torcello which we toured by a hire boat) were within walking distance. Highly recommend it for a real Venice experience!
