The direction to the apartment was accurate and clear. The location was great. The use of lock box made checking in and checking out very convenient. You can take airport limousine bus from Narita and Haneda to Shibuya Mark City, as well as taking the airport limousine bus to the airport. Shibuya Mark City is about 10-15 mins walk from the apartment.
The apartment was very clean. It is spacious for 2 people. However, if you are a group of more than 2 people, you will have to spread the futons in the living area. The shower room is sufficiently big with a tub, and the toilet is quite spacious. The washing machine worked well, and we dried the clothes in the shower room by turning on the drying mode.
There was internet access in the apartment, and it was fast, and there was no limitation in the usage. However, there was no portable wifi router provided.
We were allowed to check in early at 12pm when nobody was staying in the apartment the day before we checked in. The host was both kind and flexible to allow us to check in early.
