The flat is just a 30 second walk from both Varenna's main piazza and the lakeside - which is beautiful. Renata and her husband were very nice, picking us up from the train station and driving us to the flat. They even had bought us some, cheese, wine and salami for our time there.
On the same street are several quality restaurants and it's only a 5 minute walk to get to the ferries. I cannot imagine anyone not enjoying their stay in Varenna. We'll be back.
