I will try to be as objective as possible for this review due to the mix feelings I had during my 1 week stay.
Context:
-	It was my first time in japan and in Tokyo
-	I flew for a combined amount of 15hrs to get to Tokyo
-	I am a lone traveler and I work while traveling (IT guy here)
-	I stayed for 6 days
Pros:
-	The location was amazing, 5min away from a subway station and from there you can pretty much get anywhere you want
-	The instructions to get to the place were amazing (Pro tip, if you have heavy luggage use exit a2 instead of a1 in hakusan station, you will walk a little more to smileys house, 4min more, but you will be able to use an elevator instead of “climbing” 3 sets of stairs)
-	It was cheap
-	Great communication with the host, I had a couple of question about where to buy certain items and he/she was kindly enough to answer me really fast
-	It is really near to convenience stores (3min walking), mini markets (2min walking) and restaurants (2 nice restaurants in the first floor of the building, and several just a couple minutes walking)
-	There is a laundromat (coin laundry in japan) 6min walking, you can use the washing machine smileys has but if you prefer or have to do a bigger batch I would suggest going to the laundromat
Cons:
-	It is not a room in a traditional house, it is a room located among others where you share the bathroom and shower with a lot of people (8 rooms total in the floor) and there are a lot of people coming and going, I think it all depends on your travelling style.
-	Self check-in, this point really got me thinking, for some maybe it is really awesome but it is not nice for people that are trying to sleep. You are at the mercy of the manners of other guests, even if the rules say that after 10pm you should not make noise there were several occasions when people arriving at 11pm decided it was a good idea to take a shower and then use the hairdryer… again you are at the mercy of other people manners and if you are not a heavy sleeper this will be a challenge
-	The walls of the room were thin, I was able to hear when people arrive, left, took a shower, used the hairdryer, talk and even snore (I could only hear the 3 rooms that were next to mine), again, if you are not a heavy sleeper, like myself, it will be a challenge
Would I recommend this place?
Yes, even considering the cons, the pros were far greater for me.
