Josh was always quick to answer and help me when I asked, despite how busy he was. Very kind and enthusiastic to help in anyway he can, Josh was a great host. I didn't ask for a lot, and didn't need a lot, but I have the feeling he would have helped any time I asked.
The apartment is nice, you eventually get used to the trains, and being so close to the station is fantastic. It does get pretty cold outside the main bedroom, especially the shower and bathrooms. Wifi is pretty rough, but nothing to get frustrated about once you get used to it.
There isn't a lot of food options right around the apartment but if you're willing to take a 5 minute train there are plenty of grocery stores, restaurants and shops in the greater Shinagawa area. Overall the apartment itself is in a really quite and comfortable area (there are some friendly and not so friendly stray cats in the neighborhood, a plus for me not for everyone I'm sure) and it's no further than about 40-45 minutes away at most from any major attraction in Tokyo.
