One of the hidden gems in Tokyo.
The host is friendly and understanding and speaks good English. Nice environment, cosy. The room can be heated to a nice temperature even though it is in winter time.
The water can be heated to make yourself a nice coffee.(instant coffee and sugar and creamer and cups and spoons are free and available ) highly recommended for budget travellers. Note that there are no stairs so have a strong partner to carry the luggage up if you have lots of bags.
