I stayed 6 nights at Sho's place, and I really had a lot of fun. For two people the flat might be a bit small, but as a solo traveler, it was exactly what I was looking for. The flat is located in a rather quiet neighborhood, except for the mornings some days, as there is a moving company across the street, which tends to be a bit noisy if you leave your window open. I used it as an additional alarm clock ;)
There are more than enough convenience stores in less then 5 minutes by foot available and the subway station is also close by. Also in approx. 3 min. by foot there are many restaurants and bars. Check-in was mostly uncomplicated, but do make sure to write sown the key code you get beforehand, as I forgot to do so and without internet available, you're a bit lost...
Overall, I can only recommend Sho's flat for everyone, who's traveling by themselves, and only want a place to relax and/or work on the computer after a full day of sightseeing :)
