My wife and I stayed in Sunny's lovely and artful home on our visit to Seoul, South Korea. We were there to visit with my son stationed there for a year. He took a train from his base to the Seoul Station, we took the train there from Incheon Intl. Airport, and we all relaxed and did our sight-seeing from this lovely, custom condo. This home is really just 10 minutes walk from Seoul Station (take Gate 10, btw), just to the east and up a hill.
The accommodations were highest quality! The gracious attention to our every concern was rather astonishing! Our Hosts Sunny and her husband and their adult daughter speak excellent English, and were very helpful in getting is situated, oriented, and comfortable.
There are two very nice bedrooms downstairs, as noted. The beds are on the firm side, but reasonably so. And, you have to be able to handle somewhat steep stairs. My wife and I are in our 60's, and had no problems with the stairs.
In addition to the downstairs bedrooms (that can sleep 4), there is a sunroom with a small fold-out couch, a loft accessed by a ladder from the kitchen area, a new, full-size washer and dryer set (top quality, again), custom bathrooms upstairs and downstairs, and a *NEW* full-sized, top quality refrigerator. There is also a lovely balcony deck (teak wood?) accessed from the dining area as well.
Everything was very, very clean and comfortable! The home has radiant heat in the floors that are managed through the owners' smart devices.
We stayed 12 full days, could have comfortably stayed longer, and I would definitely stay there again if we return. We would highly recommend this residence to any visitor to Seoul - especially if you are an American like me that doesn't speak the language and needs some pointers from hosts who understand you perfectly! ;-)
