We spent two nights at Adriano. Directions and communication were excellent, check in was very easy and explained well. Adriano is centrally located very close to st marks square. We arrived via the train station and so it was a vaporetto ride and short walk to the accommodation. The room was very clean and modern. Shower worked well. The room had AC, it was not the most powerful but still very much appreciated! On the day of departure we were very helpfully able to leave our bags at the property after check out.
We would highly recommend anyone considering staying at Adriano, although others should be aware that it is not suitable for anyone with mobility problems as you must be able to walk up several flights of stairs.
