Room is just as described, clean and has basic amenities.
The room itself is fairly small with a with kitchenette rather than a full sized self serviced apartment in its traditional western sense (photos are a fair representation). The apartment block looks oldish from the outside but is older but well maintained from the inside. Bathroom was on the small side but in saying this this is Tokyo and everything is highly squeezed in. We found it comfortable for 2 people with 2 medium sized bags.
Reception is manned 24 hrs and they are always willing to help. We were lucky to have access to our room before the offical check in time - which was much appreciated.
We were commuting on our JR passes. The JR Shinjuku station is about 15 minutes walk away (also handy for the airports). The Tokyo metro (seperate to the JR lines) is 2 minutes away, super convenient if you are buying the metro day pass.
The entrance to the hotel is along an alleyway (it is safe just was not a lot of movement) from both the JR side and the metro side. Plenty of food options and in a slightly quieter part of Shinjuku. All in all we had a great time in Tokyo and room met what we were after.
