Great hotel for a short stay in Seoul this hotel is very close to a lot of local amenities, shopping and restaurants. We had an excellent stay and would return. The area is busy in the evenings so it was loud some nights but that wasn’t too much of a disturbance. The staff were incredibly helpful, there is coin-operated laundry which is very convenient. The breakfast offering is simple more continental style with espresso coffee, toast, cereal, enough to get you started for the day and with convenience stores and cafes close by if you prefer. Felt very safe as a solo female traveller with not very much korean. Thank you StepInn for a wonderful stay.

I was very surprised to see an in unit washer and dryer machine. Plus a cooking station. The room is very easy to use, a full size fridge with freezer and light switches that very easy to figure out. temperature setting is easy to use. This area is close to airport bus about 5 mins walk with luggage's may be around 10 mins. The bus station is facing the Dream building. Take t-money for around 17,000 won. I really like to stay in this hotel because it makes me feel homey. Like your best friend has cleaned up his guestroom just for you to stay over the weekend. Downstairs towards the front desk exit, make a left, you will see small mandoo shops, fruit shops and if you turn left at the end of this small street, you will see a pharmacy. If you turn right at the end of this small street, you will see Olive Young. Then you land on the big road where the aiport bus runs.

Most comfortable bed during my stay in South Korea. Bathroom has everything you need, but in a space that was ridiculously tight. in general, there was simply no place to lay out my roller suitcase. I had to open it on the floor, which limited access to the bed because the space around the bed was so narrow. The staff was friendly and helpful in general. The room was just fine, but it would be great if there could be a space for my roller suitcase to open up.
