Apartment in which we stayed in was not luxurious but just good for our family of four with two children (5y and 7y). We had two rooms with separate (quite big) kitchen. Owners of Elite Apartments are very nice and helpful.
The only problem was not pleasant smell in bathroom, but I find it as a common defect in apartments that are not occupied constantly.
It's close to food-stores, bars, restaurants and city center and to main metro station (Deak Ferenc).
I would eagerly stay in this place visiting Budapest next time.
