If you have any doubts, think it over no more and book the paprika apartments.
Tehy are in the center of budapest. really, it is just so easy to move around from there, the underground stops just in front of the apartment, no better way to move around the city.
moreover the place is really neat and clean. there's everything you need, towels slippers washing machine, and not to forget for any probem, krisztina is there to help.
she helped us out with the transer at 4 am in the morning, contacting agencies and organizing the wizzair transfer . . . really book here and you'll be just fine!
