All is in the title...
We chose this hotel because we had an early flight back home and wanted to stay close to the airport (10 minutes drive form the hotel).
Do not stay there if you plan to visit the city. It's lost in a remote neighbourhood and may be difficult to reach without a car (we had a car :-)) or to find without a GPS (we had a GPS :-)).

The building and the overall presentation seems very dated, but I have no bad comment regarding the rooms.
We experienced the restaurant of the hotel, because you can't find any other place to eat within kilometers. You can eat there, it's correct.
The staff, if not really friendly, answered positively to our requests.

Me and my girlfriend were travelling in Croatia on May 2011. First and last our stops were in Zagreb (our flights were arrived there) in Hotel Porin. The hotel has facilities of 2+ stars quality. However, at that time there were several groups of teenagers, they make noise 24x7. The noise wasn't broke our sleep, because we were so tired. The breakfast was okay, but a bit poor. I could recommend to stay there if you have no other choice. The hotel was overpriced for us.

only minus the hotel - situated. If you are a tourist, so even without a car, to get to civilization in the city should try to find a bus stop, and ride with transfers for about 15 minutes. otherwise, everything is fine: clean, quiet, responsive staff, a hot breakfast, in room hair dryer, Wi-Fi and TV in Croatian :)

We would never recommend anyone to stay at this hotel. The service was absolutely terrible and the hotel manager had a poor service mentality and understanding of specific needs and unforeseen situations. We have never experienced such a bad service before.
