If you are looking for a quiet neighbourhood, then Yu’s place is for you. It is only 2 minutes from the station and is within walking distance to Roppongi, and you will also pass by the Azabu-Juban neighbourhood, a very lively area lined with restaurants, supermarkets and coffee shops.
There are three excellent restaurants, with reasonable prices, immediately next to the apartment building which you should try out. The pizza one is on the pricey side. There are in fact at least 2 Michelin starred restaurants around the area, so you don't even have to venture out far if you are into the Michelin star experience.
On the whole, we found the stay pleasant and convenient to the tee.
