I stayed at the Lakeview Lodge during a 3-day trip (Sunday-Tuesday) trip to Broken Bow state park. The room was very clean and the staff was very friendly. Since my trip was in the low-season, I did not have any problems regarding noise from the adjacent rooms but I can see how it can be a problem if you stay during high-season and the rooms adjacent to yours are booked.
I think that in general, you may have a slightly better view of the lake if you get a balcony instead of a patio view but in general, all rooms have a wonderful view of the lake. You can probably notice this by looking at the map but I think it is important to mention that the lake is on the east side so you will not be seeing susets over the lake but, if you are a morning person, the sunrise is just as beautiful. Continental breakfast is available starting 6am and the dinning room deck has the best, unobstructed view of the lake so it was wonderful that the sky cleared up enough for me to enjoy breakfast while watching the sunrise over the lake.
The continental breakfast consisted of cereal, hot coffe, juice, milk, bagels, croissants, and muffins that are prepared daily and kept in the refrigerator for you to microwave. If you are looking for freshly made eggs, bacon, sausage and pancakes you are probably going to be disappointed. Note that there is no restaurant on-site.
There is a 5 mile hiking trail across the lodge, it is divided in 3 'loops' with increasing degree of difficulty in terms of the type of terrain they cross. I hiked the beginners trail (about half a mile) and it was a nice walk that took me about 20mins in a slow, not-rushy pace. There is also a boat just downhill from the lodge entrance and I even saw some people swimming in the lake near the shore in the same area.
The Beavers Bend State Park is a short drive away. There is a lot of activities at the park (fishing, boating, canoeing, swimming, hiking) and they even have a tennis court in the park to play some points or perfect your serve surrounded by big trees and fresh air :)
If you are looking for a nice and peaceful getaway I do recommend the Lakeview Lodge. It is a great value for the money.
