Lorenzo's place is very well equipped for a long stay. It has everything you need and it is very well furnished. The beds are comfortable for Europe. There is a TV in the living area and the internet is fast enough to stream Netflix but you will have to bring something to stream with. His TV is not a smart TV. The apartment is on the 2nd floor (in the U.S.). You will climb stairs. However, this should not be a surprise to anyone because you will climb a million walking through Venice. His apartment location is great. It is less than 10 minute walk to the train station. There are plenty of places to eat and Lorenzo recommended a few. He also walked through the apartment with us which is a nice touch. It allowed us to ask questions. He is a great host and very responsive. I highly recommend you stay here.
WARNING: Most places in Venice do not have A/C and most do not have screens on the windows. (Keep in mind finding screens for windows that are hundreds of years old would not be very practical). If you leave the windows open during warm nights you will be invaded by mosquitos. There are plug-in devices that help deter them from entering. Make sure to ask how do to this. This is not just Lorenzo's place. It is EVERY place in Venice that does not have A/C. We were inexperienced enough to leave the windows open the 1st night and eaten alive.
