Spoke with Betty through messages and met Ivan who helped with the check in and was very helpful and kind.
A perfect location if you hope to visit the Biennale and want to stay walking distance from the main two venues of Giardini and Arsenale. The apartment is very close to the vaperetto water bus stop (2-5 min walk). And is also a lovely quiet part of venice away from all the touristy hustle bustle of San Marco or Rialto. (But still within 20-30 minute walking distance from both as well as faster by water bus)
