Staying with Kotaro and Kei in Tokyo was so nice - they are the cutest couple and made me feel so welcome in their home. As well as cooking amazing Japanese breakfast everything morning, they helped me find my way around and we had fun drinking sake together! Their home has everything you need and the room itself is a good size - it takes about 15 minutes to get to Shinjuku by public transport or it's a 2200y taxi ride home after a night out. There are plenty of convenience stores and small restaurants in the neighborhood.
