First, it should be known that this is NOT an apartment building, or "licensed apartment/room". It's a HOTEL, straight-up no two ways around it. The name is of the hotel is G-Stays... so do your research before staying here. If you're into the place then great, if you have any hesitations than don't book.
We felt cheated in the listing because A) it's not explicit that it's a hotel, nor the hotel name is provided B) when we arrived we were assigned a room that was very different than that of the listing's photos (the staff later, very kindly, switched us to a better room) C) The photos are enhanced quite a bit and show more light/make the place look newer than it is D) felt we could have gotten a better rate from a travel site.
The hotel staff are friendly, and will do their best to accommodate you- however this is a two star hotel. Rough around the edges, slightly dirty, and small rooms (which yes, are typical in Tokyo where space is limited).
The main issue here is that I go to AirBnB to specifically avoid hotels. It's against the brand's mission and promise. So you book this place thinking you're staying in someone's house, but instead it turns out to be a old hotel. Not the experience I was using this site for, and not an experience I would sign-up for again.
The only reason this isn't a two star review is because the staff truly are friendly, helpful, and try their best to accommodate. I just can't get this taste out of my mouth that we were cheated.
