We are a family of 4 (2 Adults, an almost teenager, and a 9 year old) and had a wonderful vacation in Tokyo. I believe out decision to stay at Harumi's place was the best decision we took in this trip. From early on Harumi was extremely good in communicating and alerting on important things.
I could possibly not go into everything Harumi did in terms of communicating and helping us while we were planning our trip, but in short my experience was nothing short of feeling like we were going to stay with a friend. And when we reached her place - it was exactly like that in person as well. Harumi is a very kind, generous, and friendly person and it shows in all aspects of dealing with her.
The apartment was sparkling clean! Harumi had told us in advance that the pictures on her listing are for 2 beds, and that for 4 people the space might be a little tighter because she will add 2 mattresses - however, we found the space to be spacious enough for our family.
The apartment location itself is excellent as well. Just outside the apartment is the coffee vending machine with warm coffee for mornings if one is in a hurry. Just a block down is a breakfast place Nui, an excellent Ramen restaurant, the train stations. Every thing was very easily accessible.
We'd recommend this apartment to anyone without hesitation.
