This was a fun and unique experience! The mattresses are very comfortable and the capsule is a good size! We were told by staff that we weren’t allowed to use the lockers (not sure if this was a miscommunication due to language barrier, but there was no clarification about it on the listing) so we had to sleep with our luggage in the capsule. Also, while it is an affordable option keep in mind there is no fridge or microwave so you have to eat out every meal (expensive in Vienna!!!)
