It is a fresh new apartment with all facilities you may need during stay. The instruction to the apartment from the underground station is very clear so you won't miss it by following the instruction. The check-in and check-out are easy. The apartment is very close to Skytree (10 mins walking distance) and sight viewing places at east side of Tokyo. But it will take a bit time (above 30 mins) to places like Shinjuku and Shibuya. There is a school next to the building, people will use the tennis course in the morning.
