Our family always stayed at Vista every time we visit Korea for the past few years and enjoyed it very much. However, this time was slightly disappointing as they changed some things. They removed the check-in desk and turned the whole lobby area into a buffet restaurant. This was unpleasant as the check-in is now at Walkherhill, through some banquet rooms and small hallway. The buffet always had a lot of people lined up and congregating, and the people from banquet using were also very loud. Maybe its because our visit this time was during December, close to Christmas-time, but still it was rather chaotic and not as quiet and orderly as before. The facilities also showed a lot more aging.
Their room service menu also changed, and it seems (even for a 4-5 star hotel) almost laughable to pay 65000 won for a soy bean paste soup. We did order kimchi soup for 55000 won before, but small pizza and bowl of doenjang soup for over 60000 won seems odd.
Still, its a nice hotel with a reasonable price ($190-200 if you choose a room without view, with 2 double beds) with very friendly and professional staff. Oh, and the fitness center is great!
