We stayed at Eremo Gaudio in May. We really liked it. It was a memorable part of our trip. The best part is the view. We stayed in the Bellagio Room, in the upper part of the hotel. We had a spectacular view of Lake Como and the town of Varenna from our balcony. Just fabulous. We had to ride two funiculars and an elevator to get up to our room, but it the payoff is this outrageously beautiful view. The rooms are plain -- nothing special. But you really can't beat the view.
Eremo Gaudio is tucked into a hillside on the edge of Varenna. It's a little off the beaten track, a short walk from the center of town. That was fine with us -- we liked the setting of the hotel, up on the side of the mountain. We hiked from Eremo Gaudio to Vezio one morning, which was a beautiful walk. Eremo Gaudio is an uphill walk from the center of town. Don't try to walk from the railroad station or the ferry station when you arrive -- it's too far to haul your bags comfortably. Take a taxi. The staff is nice and helpful. They provided ferry schedules, information, suggestions, etc. Overall, I thought this turned out to be a very good place to stay. I definitely would go back.
