The place is in general avergage with evident signs of ageing. It really is one of those old Hiltons that the only thing that resembles the name is the name itself. Being brief here are the positives of the place..
Nice pool, gardens, breakfast
Negatives, location (needs 10Euros to get to the centre by taxi), decoration ageing, interior design 70s, rooms and wcs almost strugling average, value for money at 159 E double the poorest ever!!
Try the ones in the centre of nicossia can be that bad

Nice and clean hotel.The hotel staff is very polite and friendly, food and drinks could be cheaper! comfortable and spacious rooms! tasty breakfast with a lot of choices. Very happy with our stay, will visit again.

I arrived late in the evening for a conference the next day and despite having booked the hotel through the conference and gotten a confirmation from the hotel about my stay they claimed they were overbooked and did not have a room for me when I arrived. The actually sent me away at 23 o´clock in the evening to a filthy "hotel" somewhere else in Nicosia.

When I told the conference management about my experience at Hilton Park, they of course called the hotel immediately, as the do (did?) a lot of business with them. The Hilton Park reception lied to the conference management and told them I had never arrived to check in!

I do not recommend this hotel it has unprofessional and unreliable service!

We stayed there for 4 nights in November 2012. The rooms were ok, I would not say Hilton quality, maybe some decades ago - quite a lot of wear-and-tear. The food (from breakfast to dinner) was all very good, a lot of choices both hot and cold, the service nice. The hotel is located about 3-4km from the city centre, so taxi is a must. The pool area was very nice - the water was a bit chilly as they do not heat it in November, but the plants etc surrounding the pool were really beautiful. One can only get free wifi for an hour if one asks the code from the restaurant (presupposing of course buying smth), otherwise wifi is 6eur per hour. The conference rooms we used were ok, quite usual. Overall it was ok, but nothing special.
