Great services and staff, lots of sightseeing tips.
I booked a weekend in Hotel Gellert on this website, we got a great deal as the third night was free of charge. We stayed there last week and had a lovely time, wonderful weather so we were able to discover everything on foot. The building was breathtaking and so were the surroundings with the hill rising above the river and a short walk across the bridge to reach the historic center (restaurants, shops, old streets, etc.). The room was okay, breakfast was plentiful and the unlimited access to the thermal pools was amazing. Budapest is a nice place, we would go back anytime.
