Firstly, thanks to Yuka for being very responsive and helpful to provide instructions on where to book luggage storage: She was also helpful in allowing us to check in earlier and out, later.
We booked 2 rooms situated on level 3 (without knowing) and without lift, hence my elderly parents faced difficulty getting up and down the stairs with luggage.
Location was good, pretty close to Higashi-Shinjuku station. Check in instructions were clear however the cleaning company did not do a good job, leaving dirty and messy extra blankets and bedsheets around. The bedsheets were not 100% clean and curtains not properly hanged. The rooms will require maintenance as things are starting to break down - toilet bidet not functioning and mirrors are falling off, washing machine seems dirty and aircon heater stopped heating on the 2nd night onwards.
Yuka was informed about our main concerns but couldn’t be fixed in time though she tried service recovery. Not very value for money in my opinion.
