We had a lovely time - just as beautiful as the pictures. Linda (host Anna's granddaughter, I believe) was helpful and sweet. Good communication with a question: turns out you can order a private water taxi if you overpacked as we did and it comes very close to the flat. Not cheap but worth it to us.
The location was excellent: beautiful gardens, charming street that's more like a piazza with all needs, floating produce market. The walk to the public water taxi is short and stunning!
The people before us had broken the washer but we didn't need laundry. It was being repaired right after our stay (a weekend)
We did find the ACs and shared remote a bit tricky so ask for a good orientation.
All in all a really good stay!
