This place is in a very safe, quiet and charming neighborhood. It was spacious for Tokyo (it is a house with a parking spot) and close to supermarkets and convenience stores, skytree, station and parks, etc. We stayed there for 3 weeks while we were moving from the US to Japan with small kids and it was great. They got us high chairs and made our life easier for baby feeding. (but stairs might be a bit dangerous for small kids so you have to watch out!)
It might not be a place if you are looking for a crazy Tokyo stay with bar hopping and sightseeing but it would be great for a low key vacation since the access to places is not too bad from this place.
The management company is prompt and responds very quickly. I would recommend this place especially if you are staying more than a week.
