It was clean and comfortable. The couch did not match the pictures shown, but that was okay. We were worried it wouldn't be a good sofa-bed but the one that is actually in the house worked just fine.
The AC helped beat the heat wonderfully. We also saw heaters in the closet for any cold weather visitors. The blanket also had a heating ability. There are no drawers in the rooms, so you have to hang your clothes in the closets or just work out of your suitcases. The beds are comfortable and each fit two people easily.
The fridge is very spacious. There is no conventional stovetop or oven, but the hotplate, microwave, and toaster oven were satisfactory for making a good variety of food. There are plenty of dishes and cutlery provided but only mugs for cups. Dish and hand soaps were provided.
The wifi was fine sometimes or in certain spots around the house. Most of the time it took a bit of time to load and we had trouble streaming movies or watching video or even looking up train tickets and normal search things. The Hulu on the TV is outdated, but you do have access to cable, some yahoo applications, and Netflix. The bathroom is small but workable and the washer and dryer are pretty decent too.
The area is close to downtown and transit options, but still a quiet neighborhood. Libraries and parks are in walking distance and various grocery stores are fairly close by car. The main house does have a sweet dog they let into the yard sometimes but the owners were very considerate asking if we were comfortable with the dog first. The backyard has some nice plants and a cute sitting spot, it's a nice garden to relax in.
