We had a very pleasant stay at Giacomo's apartment. The location is nice and really close to Vaporetto and to train station so it's quite easy.
Don't be afraid by the staircase at the entrance which is (as often in Venice) not in super good condition because the apartment itself was renovated, is nice with plenty of room and that's great for travelling families like ours.
For the rest the communication with Giacomo was easy and we got fast answers. He was also proactive regarding remarks as we like to give feedback on a positive way to continue improving the apartment.
