The apartment is very beautiful and tidy and all basic things for daily life are there, towels, soap, fridge, microwave, bowls, pots etc (it only has one stove so sometimes cooking takes longer as usual because you can't cook two things at the same time).
The location is great! Eventhough there is a biger road next to the building it's not very loud, the windows are isolating pretty good and at night it is very calm. There are a lot of great supermarkets in walking distance (not only combinis!) The Sumida river is also very near, there you can walk along the beautiful riverside-walk. Also Asakusa with its great temple and old shops is in walking distance.
Although we never met Lucas in person he was very reliable with texting back quickly whenever we had a question and he was always nice and polite.
We really enjoyed our stay and warmly recommend the flat to anyone.
