I loved that the place was a 5-6 minute walk to Hatagaya station which is close to Shinjuku. The apartment is well-lit and very clean. The bed was comfortable and the apartment had adequate space for our two pieces of luggage. I especially liked the wardrobe area - it had plenty of hangars and space for clothes.
Yuka gave us very clear instructions on how to get to the place and even how to use the washing machine. Appliances were even helpfully labelled with English translations for important buttons. The only thing is that the bathroom is a little cramped for showering and I would've liked some counter space in the bathroom with which to do my makeup. Otherwise, we had a fantastic stay!
