This is our first time using Airbnb and am very impressed with our host Koichi. He was very responsive (usually within same day) when I text him enquiries before our arrival. He emailed me very detailed maps on how to get to his apt and how to obtain apt key from a lock box. But to my surprise, koichi text me 30 mins after I landed in Tokyo, asking me if I had arrived. Told me he will wait for me by the roadside since it was dark and may be hard for us to find the place. It was nice of him to do that as taxi driver had a little difficulty in looking for the lane. And he helped us lug our luggages up to apt. The apt is one floor up and has no lift but only one short flight of stairs.

Although located in a small side lane, it's very safe even to walk at night. there's 24 hrs mini mart round the corner and a lot of small little restaurants nearby. Very good location, very central to big shopping centres.

Walk to Shinjuku-Sanchome metro station, East Exit is less than 10 mins. I didn't time our walk but may be faster without children. But beware that in Tokyo all the underground walkway are long walk to any exits and lots of steps (most do not have escalators or lift). So if you have lots of big luggages or children in pram, it's better to take the limousine bus to nearest hotel/stop then take a taxi.
Apt was clean and he has lots of towels available. Didn't restrict us to the use of just one towel each. Kitchen very basic, just for light cooking. Has microwave oven too. Very comfortable for 4. May be tight for more than 4 if you have a lot of luggages.

We were going to Takayama and Shirakawago after Tokyo and had trouble booking our bus tickets. Koichi offered to help us make calls & book the tickets for us. His office is just round the corner (5 mins walk).

During our short stay (4days) Koichi text us a few times asking how our holiday was getting on and if everything was ok.
On the day we left, he offered to drive us to Tokyo Main Train station!
What a wonderful host. I will give him 6 stars (if possible) for great services. He made us feel like friends. We will definitely come back to stay with Koichi again.

Koichi has 2 other smaller apts beside this apt, so if you have more people travelling together you may rent all the 3 apts in a row!
