My family and I stayed here for 2 weeks for Christmas. I am from Oswego and usually stay with my parents but we wanted our own space to work from so we could stay longer.
First, I missed in the listing where it is a unit, not an entire house. It is the back part of a house. It wasn't a problem for us, but the people in the other side of the house could be loud (I'm sure they could hear us too). My kids are 7 and 9 so we didn't need it particularly quiet but wanted to mention it for others that may have smaller kids.
Second, the listing pics do not show a TV, but there was one a Roku TV in the living room with Netflix ,Hulu, etc.
Third, we worked from the apartment and the internet was sufficient. We did not have issues with the internet. There is a dining room table you can work from but I borrowed a folding table from my parents so we had more desk space.
Fourth, water pressure in the shower was great. Very hot water. Be careful if you have kids, the water can definitely scald you.
Fifth, location is awesome. I recommend this location for the summer/harborfest. Walking distance to downtown, breitbeck, and Franklin square. You can see the lake from the front yard. Quiet neighborhood.
Sixth, property manager was very communicative and responsive but we never interacted in person (which is my preference personally).
Seventh, we had everything we needed to stay. All the pots, pans, dishes, soap, toilet paper, paper towels, bath towels ,etc. It was fully equipped. There was even cooking oil and spices. There is no dishwasher or washer or dryer (but there are a few laundry baskets so you can transport laundry).
Eighth, the place was very clean, but it is definitely old. It was completely sufficient for what we needed but not fancy. As others have mentioned the floors are very uneven. The stairs are kind of steep. My kids didn't have an issue but if they were smaller it would have been more difficult. My husband fell on the stairs several times (he is fine).
Overall we had a great stay and would stay again.
