I stayed there for one week with my boyfriend. Excellent value for money. Budapest in general is very cheap as they dont have the Euro thank god!
It had all the basics in the studio apartment including a washing machine. It has good transport links. Its close to the tram, train and you can also walk to the city centre.
The locals are very friendly. its good for a weekend break.
Improvements that could have been made - Internet and TV would have been appreciated as we were staying for a week.
