I just came back from Budapest where I spent the whole weekend with my friends. Choosing Grund hostel was great decision: For me as a student, price of the accommodation always matters. Grund offers reasonable prices and besides that it's located in nice peacefull area only +-10min away from the downtown by train or subway. Receptionists are so helpfull and friendly in every situation: we got even nice recommendation for local restaurant which is not "touristy" but favorite between citizens.
Looks like that Grund still hasn't been finished because they are making it bigger & bigger and downstairs is a huge club which might somebody disturb while sleeping- especially during the weekends... But for me as a young guy who came to enjoy the Budapest night life as well such a just ideall option. Thumbs up & keep it up Grund crew!!
