The capsule bed aspect was fine but i personally wouldnt stay somewhere like this again. My first impression of the hotel was walking into an elevator full of trash, so that wasnt a great start, but the other areas had seemed decently clean and it didnt happen again the next day. Its not the staff or administrations fault, obviously, but its difficult to sleep due to the noise of everyone else around you. Youd think people woild be better about it, but people are wildly loud when getting up. Loud unexplained banging, loudly opening the door to the room and then leaving it open so you can hear them be loud in the bathrooms nearby, alarms not set to vibrate so everyone has to wake up with them.
Ive learned that i like being able to access my room/luggage whenever i want, as i found it a little awkward not being able to access my locker during cleaning hours (10am to 2pm). Its totally understandable that it works like this, just something to bare in mind. I think a 1 night stay would be okay as you wouldnt be affected by this.
If you snore, do everyone else a favour and stay somewhere else
