The lovely Budapest bubble is located right next to the city museum and only a block away from the main pedestrian zone and the little bohemian center. The oldest food market is 2minutes away from it as well.
Its close to the metro stop so its easy to reach from the Keleti train st.
The hostel is small and very cozy and staff make up for everything you might have in ind but don*t see hows that possible
Its a real hidden gem and i recommend it for laid back backpackers
