Hotels met zwembad in Yerae-dong

"The hotel did not meet the expectations for a 5-star hotel. The staff spook very poorly English. They could not wash our clothes (4 nights stay) despite the laundry service offered. The clothes would not be back for 5 days despite the 2 days they promise it would take. Very unfortunate. The sunbeds at the pool were terrible, no comfort at all, no pillows or anything. Beds were very small, eventhough we booked a twin room, you expect at least a 180 cm bed. And the bathroom is very outdated - a shower in bathtub… We are not returning to this hotel! "
