My Dear Guests,
Inspite of being not in the city-center I think you can have a very comfortable, cosy accomodation for a very reasonable price with a small balcony where you can have a rest in the fresh air.
The public transport in Budapest is well-organised, with a travelcard you can visit all the attraction. The apartment (50m2)has 1 living-room with a flexible bed, 1 bedroom with a double-bed, a kitchen, a bathroom, a toilet.
And you can park free in front of the house...
