Our stay was for the weekend in the green Art Deco room and we have no complaints. Nice, clean and stylish apartment. Friendly reception and good service. No issue with card or cash payments, both are accepted without any issues. We texted the owner 1 hour before arrival and they were waiting for us on arrival to hand over the keys. We even got extended check out time as the apartment was not rented for the next day.
For us this was a good experience to Budapest and we will for sure rent the same place again when we return for a weekend in the summer.
