Stayed for one night at the Seoul Renaissance in Oct 2008.

A very nice hotel overall.
The hotel is about 1 hour away from Incheon airport.
We stayed at the Club level and hence had access to the club lounge.

The spread at the lounge was very nice with good snacks and also drinks in the evening.

Rooms very not as bright as I would have like to have, but were typical of Renaissance... nice and clean with a bathtub and good shower.

Breakfast at the root top restaurant was good with a panoramic view of the city.

This hotel was a little older than some of the other hotels, but I did not have any complaints. The downstairs lounge had live music, the lobby was really nice... and this was a Marriott chain. The room was clean, the hotel gave you free bottles of water. Overall, I enjoyed my stay at this hotel. And there is a Korean Air limo bus that will take you straight to the airport. Very convenient.

Very good hotel, everything so clean and working. We were also lucky to get very good deal for these nights.
Also very convenient bus connection to Seoul-Incheon by KAL Bus.
However, for a tourist trip you always need metro to get where everyhing nice and interesting is. And metro does not run all night, so taxi back to the hotel. But if prepared for that this is a great hotel.

Typical of Renaissance hotels, the lobby as large, with high ceilings. The room was plush and we had a view of the busy street scene below. Smack in the middle of Seoul's business district, the hotel is within walking distance to a good variety of restaurants. It is far from shopping areas and tourist sites, however. We had to take either a cab or the subway to go to Itaewon and other locations.
