The apartment is small but really cosy and well distributed. Be careful with the stairs if your luggage is heavy.
The check-in/out procedure was very easy and the communication with June was quick and polite. I booked the apartment after arriving to Tokyo and after 2 hours I was checking in.
The location is just perfect! The area is quiet at night, so you can sleep well, and it's easy to get to any of the most popular areas in Tokyo by train, you can even walk to Asakusa.
I recommend June's apartment if you plan to stay in Tokyo for a few days.
