We had a great time at Pietro's place. The location is amazing literally in between Rialto bridge and San Marco, a few steps from each. Air conditioning works great throughout the house; we were there during one of the worst heat waves of the last years and had no problem cooling the whole place. Wifi/Internet was the fastest I've ever experienced in Italy, i ran the speedtest app from my phone after connecting and saw it go over 500 Mbs!
