Check in guide was not updated with the latest photo of the lock and the building looked slightly different due to the shop beside. Although the password is the same, the different lock was abit hard to use, made us thought that we got the wrong house and took some time.
When we had problem with checking in, host did not respond until 3 hrs later, and is by the management although we contacted during their 'office hours'. Moreover, we were somewhat blamed for no Japanese phone number to call them for help. However would not affect guests with Japanese contact number.
Location wise it is very near the train station which is good, convenient to shinjuku but not other city areas like shibuya as need to change line. Moreover, it's located on their local line, all announcement was in Japanese and interval between each train is longer compared to other lines. Have to be more attentive when taking the train. It is also located right beside the train track so might not be ideal for those that are very sensitive to noise. Moreover, during our stay, there was construction going on right outside the house for the train which is only conducted at night, was pretty noisy and the host did not tell us about it, the construction might last for quite a long period too.
When we stayed there, the temperature is on average 10 degree celcius and the warmer was just ok, the floor was very cold with no slippers provided so that's a slight down point but love the fact that they have 3 queen size beds and condiments provided for cooking!
