We had a great stay in the Aria Hotel in Budapest. We stayed there 3 nights mid april and enjoyed about everything : room, amenities including the hot spa, the very nice wine and cheese with live piano at end of the afternoon, great dinner and breakfast. Service was very friendly and helpful. The room was top, bed, cushions, equipments, etc.
Location of the Aria hotel is ideal : centrally located in Pest. Quiet street, only several minutes from the pedestrian streets, metro or St.Stephen's basilica.
In the evening, a lively rooftop bar with music gets quite a lot of visitors, so for quieter rooms, ask levels 2 to 4.
We would definitely love to come back !
