This is a very nice apartment and very big for this area in Tokyo. There is everything you need available. Koichi is a very good host and cares for everything. The surrounding is very nice and close to the heart of Shinjuku.

The only problem was a construction site directly opposite of the apartment. So from 8 in the morning it was very loud and impossible to sleep.

So I recommend to ask Koichi if the construction site is still there - because besides that I really can recommend this apartment.
