We've had a wonderful stay (2 nights) at Penny's place. We've rented bicycles in Martinborough and enjoyed a tour along the wineries in the area, and we've had a nice lunch+wine tasting at Poppies.
We stayed in the little house in the Garden where we enjoyed the comfy bed and all facilities available. Penny was very welcoming and gave us lots of tips on where to go and what to do.
