We stayed at Daigo's place for 4 nights in July 2019. It is a decent size by Tokyo standards. Our 2 teens slept in the little bedroom and we had a real bed in the living area. The bedroom even has a projector to watch You Tube on the wall - the kids loved that. Everything is new and spotlessly clean. He even provided coffee for the morning. There is a portable wifi for your use, which is great because we didn't have cell service in Japan. The apartment is in a quiet residential area, which is what we wanted - you get to feel like you are part of a real Japanese neighborhood. It is close to the Skytree which has shops and restaurants(and is also very cool to go to the top if it is not a cloudy day), and a 5 minute walk from Oshiage station (Daigo provided photographs of the route from the station to the apartment, so it was easy to find the first day). There are lots of convenience stores nearby (for all your essentials, beer, sake and great pre-made food), and some nice local bars and restaurants. The area is very safe, we let our kids walk around by themselves (ages 14 and 12). I would definitely stay here again the next time we are in Tokyo.
