Thao & Tran is very friendly, they communicate well in English and since the beginning their responded very fast to all of my massage.
Location is not in the centre of city (around 30-40 mins train from main station), but the access is good, only 2 minutes walk from nearby station (it was literally beside the train station) and easy to find.
Check-in & Check-out time was flexible. The owner (Tran) was staying there on the 2nd floor while the guest rooms are all on the first floor (there are 2 guest rooms). He made time to greet us and gave us quick tours when we arrived although all the manual was already described in the complete guide he emailed me.
It was a new building, the room was clean and tidy, futon beds, carpet, air-con, and wardrobe big enough to store 2-3 luggage. Very comfortable. The room was considered spacious for 2 travellers (compared to the other BnB I stayed in Japan), just nice. One share bathroom for two bnb rooms and separated toilet. All clean and tidy. Laundry also available (we didn't use it though). Internet access was good.
Neigbourhood was quiet and friendly, it was in a small clustered resident area, and everybody would greet you when passed by. There are a fast food Japanese restaurant and big supermarket nearby (below the train station).
Me and my travel partner really enjoyed our stay there. Owner was really friendly and sincere. They also give us extra mile service. It was a satisfying experience staying there and will definitely look for this place again if i have chance to visit Tokyo again in the future :) Well done!
