Helmut's place is absolutely gorgeous! The view is even better than it looks in pictures and the place was more spacious than I had anticipated. All of the rooms, even the bathroom, are huge. The kitchen is fully equipped for cooking which was perfect for cooking dinner one night. The back of the condo overlooking the water is all windows and french doors with a terrace/porch lining the entire back so you constantly have a view of the water. We spent a lot of time just taking in the view with a cup of coffee in the morning and a glass of wine at night. If you are looking for a quiet place to stay with breathtaking views, this is your place!
If you are looking for a place to stay that is walkable to bars and restaurants then Hamilton Cover is not your place. However, I would highly recommend staying here over a place in town. It is absolutely worth it. Avalon itself is small and this condo is not far from the town center but if you are going to drink then you will (or at least you should) take a cab. This will cost you about $14 cash each way. During the day (or if you are not drinking at night) you can use the golf cart that comes with the condo which is a great perk and very convenient for getting around!
Overall I would highly recommend staying at Helmut's beautiful place. I was truly sad to leave and can't wait to return one day!
