Me and my wife stayed there for a three days. Very quiet location away from the busy tourist places, but near to Via Garibaldi where you can find many shops, restaurants, there was even street market with fresh fruits and vegetables. Ten minutes walk to San Marko, just a few minutes to vaporetto stops or to the park.
We didn't meet Harald or Valeria, but they had gave us all needed information about the flat before.
The flat is nice and cosy and we enjoyed it a lot.
