Location, location, location! This place is the best! So close to St. Mark's Square where all the action is. We love having the luxury of resting at this place during the busiest times in the morning and afternoon when all the group tours and cruises come to crowd St. Mark's square. We were able to stay out late at night since we are so close to our AirBnb. Would stay here again the next time we visit Venice. Communication with Marta & Chiara was immediate. We had a problem with the A/C, but they took care of it right away. The rooms are clean and bright. The bathroom is a good size. Wi-fi worked well.
Just a note though about their unusual check-in. It wasn't a problem for us, but it would be good to note for future travellers. You have to check-in at a concierge office about 10 minutes walk from the train station before your hop in a vaporetto and head to where the apartment is. We were a family of 4 with 3 carryon luggages. So what we did is I went to look for the concierge place to check all of us in while my family waited for me at the train station. This way, you don't have to all walk with your luggages (through the crowd and 2 bridges), then have to come back to the train station where you catch the vaporetto across the street to St. Mark's (45 min.) to get to the apartment. Make sure you have everybody's passports and payment for the city tax. You need to fill out some paperwork and they have to go over the rules so plan for a 15-20 min. check in. Again, it wasn't a problem for us since all the instructions is clearly stated in the booking instructions.
