The Westin Chosun
The Westin Chosun is among the nicer Westin hotels we have stayed at. We loved its central location with almost walking distance to most of the sites we visited in Seoul. ("Almost" because we consider anything less than 25 minutes a walking distance - we fitbit wearers always love some extra steps!) The rooms are modern and decently sized. There is a sleek gym with a an indoor pool.
The hotel also has a cute dessert shop called 'The Menagerie' on the first floor run by a famous award-winning pastry chef. Definitely check it out if you have a sweet tooth!
