had the most pleasant stay at Mangrove Sinseol in my recent trip to Seoul! The room was spacious, and the staff was easily contactable through an online chat (very responsive too). Mangrove Sinseol is conveniently located near Sinseol-dong station, with a direct bus (6002) from Incheon Airport. It also has many bus services nearby that directly connects the place to other tourist places in Seoul. Would definitely stay here again the next time I visit Seoul.
