We thoroughly enjoyed our stay at Julie and Nao's place (rias). Considerung the lack of space in Tokyo it is a quite spacious flat equipped with all you need for exploring this megacity. The location of the flat is just perfect within Tokyo in a central area from where you can easily get to all the places. Julie and Nao are great hosts, we enjoyed chatting about japanese culture and language over some beers. Great place in a great city.
