Stayed in Budapest Hilton recently. Upgraded to Executive Room with river view as Gold. A box of chocolates and a bottle of wine as gifts. Free bottle of water every day. Restaurant is good but very expensive. Very nice hotel right in the middle of the tourist district with churches museums and palaces.
If you are looking for walking around the Buda side this is a nice location. Best to walk around in the early morning and late evening hours. Hardly any night life on that side of the river. If you are looking to be close to city life, you are better off in the West End as a location. I have not stayed there.
