We very much enjoyed our stay at in Shibuya at Hajime's place!
The host - Hajime was very friendly, met us at check in to show us everything and give us the key. He was very responsive on text and was accommodating with late check out for us, which was very much appreciated.
The location - In a quieter southern section of Shibuya that is closer to Ebisu. The neighborhood has an awesome Izakaya around the corner that had really good food, a popular coffee shop, and other good restaurants around it. There also is an extensive super market two blocks away called Life.
The place - It's a typical size of a Tokyo apartment, small but functional and nicely decorated. Just have to be careful on the stairs to the loft, as they are steep. This spot may not be ideal for someone older or disabled. Kitchen is small, can make breakfast but be prepared to eat out :)
