The keys were stored in a lock box and I had to prompt for the details as the host forgot to send. The apartment is in an older building but has modern amenities and was nicely renovated. The location was really convenient for access on arrival from Haneda airport and for our week exploring Tokyo due to the proximity of both subway and JR stations. There are heaps of food options closeby and a great supermarket near the station. Beds were comfortable. Overall we really enjoyed our stay in this apartment. The only issue we had was there was no iron to iron our clothes after using the washing machine.
