Stay

So, decided to post a new question rather than adding to the awesome replies i had on my previous one! Whats your view/experiences on airbnb satys in Tokyo ( and Japan in general)? Reason im asking, they are considerably more affordable (half price at times) from hotels and double the space a hotel offers you. Ive had mixed results and responses ( late responses, no answwers to questions etc) from hosts when i contacted a few of them but their reviews are great! Also is bnbing still illegal over there?
