Good space. can easily fit 5 people. but for 6. it's kinda cramped but still okey !
the host is VERY nice and responsive. she replies go my text very quickly.
she got us a pack of heat pads for free which is very very nice of her !
she also got us local tips for restaurants.
for the space it's better if you dont bring big luggage. if you have big luggages. it's kinda hard to bring it upstairs.
the neighborhood was nice and quiet. a bit far from the hustle bustle of the city and the keio line is not free if you buy 24 hours subway pass
overall it was nice and would recommend.
