I was here on a 2d1n business trip and I was picked up by the hotel limousine from the airport. The 1-hour ride was long but extremely comfortable. Check-in was a breeze and I was greeted many times by the staff from the doorman to the concierge to people just standing around to offer help to guests.

The room was beautiful with a modern design. There was also an iPhone for guests and it can be taken out of the hotel room for use when shopping or travelling.

I needed help with directions so they were helped write down instructions to various shopping areas in Korean so that I can show the taxi drivers. There is also an underground shopping mall that connect Coex to the nearest train station that was about 10 mins walk away.

A beautiful hotel, great service.... too bad I didn't have time to explore the various facilities.

Wished I could stay longer.

Nice hotel with very helpful concierge who went all out to print out the map in korean so that the taxi driver could understand, and patiently answering all our queries.
Lotte duty free was just downstairs. Awesome buys for beauty products from Face shop and Nature republic. Additional 15% discount if you pay with a visa platinum card.
Just a pity that the hotel is far from most tourist attractions. Takes almost an hour by subway to the attractions at the northern bank of Han river

Good hotel for business, although the high Internet charge is not very business friendly.
Rooms are comfy and the staff are friendly and helpful.
I didn't eat here so can't comment on the restaurants or room service
