We stayed here with 3 adults and one small dog. It was great we each had a bedroom and didn’t have to share.
Location is approx 10 min from Koenji station. Seven Eleven and 24hr grocery store is just around the corner but the neighborhood is very quiet and you’ll hear no noise once you’re in the house.
The place is fully equipped and we had everything we needed, especially the washing machine with dryer was useful. We also enjoyed doing hot pot and yakiniku using their Bruno!
The three downsides are;
1. it’s really cold even using the aircon full time. Maybe a heavier curtain to cover the windows would help.
2. Living room Aircon needs deep cleansing. All three of us started sneezing the moment we turned it on.
3. Another is the pet fee. 1500 per night seems a bit much for one toy poodle. We took the deal anyways because it was really hard to find a place that allows.
Overall we had a good relaxing time.
