I didn't know that I needed to buy even a toothbrush and toothpaste. There's no outlet around the bed. I couldn't turn off some lights in my room. It's a bit far from a bus stop to the Incheon Airport.
The hotel Riviera is a great hotel. I would thoroughly recommend it for business visits. I do not recommend it for tourist visits. I had a lovely stay there and I found it challenging to get tourist information (what buses to catch etc) the staff were very helpful and tried their best. It is all about horses for courses and my thoughts were if I was going on a business trip to Seoul I would definitely stay here, but for tourism next time I would probably stay in Myeongdong
