Honest review here. If you are staying with your toddler, u might want to reconsider this place. Throughout our 4 nights stay, there were constant ongoing ambulance and fire engine siren throughout the nights- it makes it frustrating to sleep and there was constant mild ringing coming from outside the balcony. The place was so so small, once u put 1 luggage, there is no walking space already. The bed was made of poor quality, very springy. On our very last night, next door neighbour woke us up at 2.20am, they were shouting, screaming, throwing and slamming things. It lasted for a gd 30 mins at least. My toddler woke up crying and inconsolable.
The only positive is the location. It is a 4 mins walk to nishi shinjuku station. This place is for those who are heavy sleepers and can survive in a cramp unit. Not worth for the costly price. I could easily find something elsewhere.
