The Mount Adams area is a walkable and safe place to stay. We were here to visit family, who live nearby. The home is very spacious and homey and is equipped with everything you'd need for a comfortable stay. The kitchen has everything you need to cook a meal (minus the food part). The beds are firm but comfortable. Be aware that there are a lot of stairs here from getting into the home itself as well as a nice finished basement and upstairs bedrooms. The only drawback we had was the street parking-if you get parked before 5:30 you will probably be close, but after that...you may be blocks away. This is a very common problem in this area, though, and not the fault of the owners. I just thought I'd mention it in case anyone has issues with parking and walking.
We'd highly recommend this rental and will consider again when we're in the area next time.
