I stayed for a few nights in a female dorm. My experience was great, particularly due to the amazing staff hospitality! The location is superb in terms of access to public transit, tourist attractions, places to eat, etc. Communication with the host was always very good and efficient!
I was quite happy to have restful nights: the capsules are well equiped, the beds are very comfortable, the room was quiet and everything is designed to make your stay as convenient as possible.
Overall, the place is clean (there's room for improvement when it comes to the washrooms though) and very stylish. It's the perfect place for the minimalist traveller, not so much for those with large and/or heavy luggage, as there is no elevator in the property.
I definitely recommend it!
