Excellent apartment, amazing location, great host, no crazy house rules.
Coming from the US it's hard to accept the scale of everything. I was able to walk from the apt to the far east side with two kids in 20 minutes. Everything around San Marco square was easily 2-3 minutes.
I traveled with my wife and two young children (less than 3). Francesca set up a crib for my youngest. The sleeping area is basically one large room with a rolling wall door divider. Easy for my oldest to sleep in his own space.
Small elevator assisted with getting up and down but the stairs are fine.
Francesca's connection to the hotel next door made check in and bags easy. They we're also great with getting a taxi to the train station on our last day.
She's has several recommendations for local dining and getting around.
Would absolutely stay again.
