We are a group of 8 travelers, 6 adults and 2 kids, who travelled by 2 cars. In term of accessibility, I'd say that the house is great for those who will travel with cars since you can park it in front of the house to load and unload the luggage. Once you finish, there's a nearby parking lot that cost only 900 yen for 24 hours (Considered inexpensive for Tokyo). Talking about the location, the house is located on the residential area of Taito, so at night there might be nothing much you can do unless you walk 10-15 mins to Asakusa area. There were two nights that we went out searching for a place to have dinner but we ended up came back home and cooked ourselves for both nights.
Check in is easy with a passcode that Aya would provide before arrival.
The equipment/appliances are all in good condition, one thing I'd like to add is that should the house have the dryer for clothes after washing that would be great. (The washing machine might have that function already but we could not manage to work on that). The kitchen section is under the stairs and small; but enough for easy meal.
In term of space, there are 3 main bedrooms, one on the first floor with double bed and two more on the 2nd floors (I'd call room B and C). Room B has two mattresses while Room C has two mattresses on the floor and two more on the mezzanine. Although the mattresses on the mezzanine are as big as others but the way you have to climb up and down and the height of the ceiling makes me feel that they are good for kids age 10+. I also would like to mention that 3 full bathrooms here also make this home a real gem for those who travel in large group.
Cleanliness is 10/10.
Something worth mentioning is that Aya is very kind and responsive so you don't have to feel afraid should there's something wrong. We had some difficulty with the house on one night and I decided to contact Aya around 11:00PM local time. She managed to help us solve the problem to the extent that we had never thought of. Thank you very much, Aya.
