The apartment is very modern and a good location, not far from the Danube river on the Pest side. There is a spar and tesco just down the street for easy access to food, water etc. and there is a shared kitchen within the apartment you are free to use.
The office was about 20 minutes walk away from our apartment which was more than expected so we arrived after the 11am check out time but they were absolutely fine with it and were happy to keep our luggage until our transfer (they sorted it all out for us) was due to take us to airport.
We had a slight problem when arriving due to the building changing their pin code to get in but the guy signing us in resolved it and spoke good English. He gave us a discount for the slight innocence too.
Me and my partner would definitely recommend Hi5 apartments!
