Myself and five friends stayed in Hae-Oks place for four nights. It’s very central and close to the S-Bahn station and walking distance to most tourist attractions. Apartment was spacious and heating system was effective. The showers were hot too. However, the cleanliness of the place needs to be improved. We all found hairs in our beds which was very unpleasant, the kitchen also could have been cleaner. Fridge was unclean along with some of the crockery and cutlery. We didn’t expect luxury nor did we want or need it however you would expect the place to be clean especially when paying a cleaning fee! I hope the cleanliness of the place improves for other travelers as the apartment is in a great location.
