We had four people at Yuko's place, and it was nice and spacious, especially by Tokyo standards. There was a lot of kitchen amenities which we appreciated, and although it is quite far from Shibuya, we liked the Ueno area and it was nice to have a quiet neighborhood to return to. We just got a bit lost on the street trying to find it - the description says 'next to the Asahi machine and barber shop' but its actually the third Asahi machine you pass and the second barber shop.
