This was such a charming home! We stayed on the second floor, which was very easy to access. The door lock used a code, so there were no keys needed or special techniques to learn. There is no elevator, so if you have a lot of luggage, perhaps ask for a lower room for less stairs to climb.
There were two double beds (we only used one) as well as bedding for another person. There are infant service items available, as shown in the pictures, but we did not need any in the process. Be careful, they are very comfortable! It can be hard to want to rise for the day with these being so nice.
We used the laundry twice, it did a good job, though do note that it only washes, without a dry cycle. This is probably standard, we did not plan. The room provides plenty of hangers, so air-drying was perfectly fine. The bathroom & toilet were perfect, plenty of room and quickly providing hot water as desired.
Location wise, it is a good 10-15mjn walk from the main Asakusa station (or half that from the Asakusa TX station). So if you fly in to Narita Airport, it will be plenty of walking ahead of you.
But, the location is perfect if you plan on visiting Sensoji Temple or the areas nearby. A very beautiful area both during the day and at night.
Chisaki was a super awesome host, answering questions before and during our stay quickly, even giving some helpful food recommendations close by.
