The lobby service is good. However, when I use masage service, their servants attitute is friendly but not quite professional. The manager asked me (I am customer) the customer is female or male because he "though" I am the masager when I checked out. It is OK for me but other customers may think it is a little bit irrespected. Secondly, I suggest to put a basket to put towels in Sana area. We did need many towels when using hot spring service but when the towel is wet, I did not find good place to put. It is not convenient. I find there are many Korean customers in this hotel but the servants in Sana area did not know English well. I think it is better to train the servant English. Finally, when I took shower in my room, I find the plunge is not so good and the water accumulate a lot in my shower area. Generally, it is a good hotel but I hope the servant can be more familiar with their service.
