Mostly I really enjoyed my stay at this place and I’d rent again! It is way more spacious than any hotel in the same price point (downright expansive by Japanese standards!) The apartment was very safe, cute (with balcony!) + in the PERFECT location in the city in my opinion, just a fifteen minute walk to Shibuya, Nakameguro etc. w/ a lot of great coffee shops + restaurants around.
My only issues were that the key was not in the awkwardly long walk away (10-15 min) from the apartment key box when I arrived so check in was a hassle, though I appreciated that they allowed early check in for a fee.
There is also no full length mirror — this is annoying but what really sucked was there is only a very small, badly lit mirror in the bathroom AND no bathroom outlet so it was impossible to use the hair dryer unless you did it blind.
Lastly, they do not mention in the listing that it is across the street from a loud, train line that has trains going by constantly (earplugs were provided).
