Yu's place is very clean, modern, and located in an accessible area of Tokyo. It has all the amenities you'd need for both long and short stays in the city.
It's really close to a subway station that allows easy access to both East and West Tokyo, so for first time travelers trying to visit as many cities as possible, this is a great place to stay. It's also on the doorstep of Tokyo Tower, so if you're looking to visit Skytree or One Piece Tokyo Tower, it's really convenient.
The one thing I'd add is that it is in a more residential neighborhood, so there aren't many dinner or nightlife options available within a 10 minute walk. We're lazy, so it was a big deal for us. It might not be for you. There's a great restaurant scene on the opposite side of Tokyo Tower park.
Yu was very communicative and helpful during our trip. We'll definitely look into staying again.
