We loved our stay at Mark's on the water. Mark was super responsive, brought 2 extra life jackets that were missing. We did not even see him but he was always available to answer questions.
The use of the kayak was awesome. The pictures on the website do not do justice to the place. It is super quaint, couches were super comfortable to watch movies and read book or just chill. We spend most of our time on the deck looking over the marina. You get the sun rise in the morning on one side and sun set in the afternoon on the other side of the deck. BBQ works great and easy to use. Great appliances in the kitchen and spice galore. Families of ducks and geese came to visit hoping for treats. It was hard not to give them any but we enjoyed watching them so close to the deck. Obviously someone has been feeding them because they were quite offended that we did not have anything. They stuck around for a while but moved along when no treats happened :).
I would suggest that If you plan on having a meal at the restaurant across from Mark's place, make sure to make reservations ahead of time. We hoped to have dinner there after kayaking for a few hours. When we got to the restaurant, we found out it would be an hour and 1/2 wait :(. We ended up coming "home" and ordering out instead. We will plan better next time.
We thoroughly enjoyed our stay. Wished it was longer. Hope to be back. Highly recommend it.
