We had a pleasant stay at this basement apartment. There are stairs down to the entrance, and those were not an issue for anyone in our party. It was very clean and the host responded quickly on the few occasions when we contacted him (such as to change the thermostat).
The location is convenient to main roads in the area, and in a safe and quiet neighborhood.
We enjoyed the large dining table and the limited kitchen (no stove) was absolutely workable for our 5-day stay. The sink, refrigerator, microwave, electric kettle and coffee maker were all we needed. There is a nearby Wegman's grocery store that had many prepared dishes that we could heat in the microwave. There are also many restaurants in the area.
We were aware that there are people living upstairs, but there was generally little noise from them, and nights were super quiet.
It was a very enjoyable stay!
