Lara's apartment is centrally located about 3 mins from St Marco's Square and roughly a 8-10 min walk from the water taxi station (only 1 bridge to cross). My phone’s GPS was a bit wonky getting there but eventually found it. Apartment was nice and functional. No major complaints.
For future bookers, please note that the apartment doesn't have wifi listed as an amenity, and although there is wifi available in the apartment, it most likely won't work. The 4G on the four iPhones we brought with us had similar service issues - we had issues outside a bit too. Neither the 4G/internet worked consistently, so don't expect video-streaming or even IG-scrolling.
Check-out was at 10am so we went one street over and put our luggage in a few lockers - easy enough.
All-in-all, a clean flat, a very responsive owner, an amazing location!
