Lánchid 19 is offically a 4-star hotel and that means some missing facilities like gym and spa, but they do have very nice meeting facilities in the basement. The most important thing is always the service and it was very good. Kind, helpful staff and you get more for your money than you would expect. Starting from 80 Euros you get a nice, comfortable little design experience to the portfolio while exploring the great city of Budapest.
My opinion: Good+ experience.
