We had a group of 20 people comfortably stay here. The rooms were large and I was talking with the owner and the mattresses are all brand new!!! The house was a 2-minute walk to downtown to where there was a coffee/ smoothie place, an ice cream parlor, a hot dog stand, and much more. The weekend we stayed, there was a great farmers market as well. Lastly, we had a 10-minute walk to Dewey beach. Awesome, clean lake beach with free kayaks and paddleboards to take out on the lake. There was also a snack shack there with ice cream and quick snacks.
Back to the property... the backyard was a great size and the driveway comfortably fit 15 cars and could easily fit more! There is a two-car garage as well but we didn't use it. We grilled one night with the large grill the rental had. Large dining room table and living room to gather at night times. Plenty of bathrooms (I think there were 6) and very good WIFI.
Overall I would HIGHLY recommend staying here. The house was clean upon arrival, Spenser is a very nice guy who let us know all the good spots in town, plenty of room for large groups, all at a very affordable price.
