This apartment is amazing, the location, amenities and overall style make it an extremely great place to stay in Tokyo. There is plenty of space and light, with a decent kitchen equipped with large fridge and microwave. The view from the balcony of Chip park is incredible that looks great year-round.
It's close to Shinjuku station (15 mins walk), which means getting to any other part of Tokyo is a breeze. There's plenty to do in Shinjuku, but there's also Yoyogi park and Harajuku/Shibuya just down the road.
Tomo is a great host who is very easy to deal with, quick to respond and very helpful. We would definitely stay at the apartment again, highly recommended.
