First time traveler to Seoul and would like to know if there are hotels that are conveniently located for exploring the city (primarily by walking). Information on conveniently/centrally located neighborhoods for walking would be helpful, too. We are currently booked at Dormy Inn Premium in Garosugil, but I'm not sure how good the location is.
As an example (for those of you who are also familiar with Taipei), my family and I recently stayed at Cosmos Hotel Taipei, which is next to Taipei Main Station. The location was terrific because we could walk almost everywhere and easily take the metro to the parts of the city that were a bit too far for walking.
