Hotel is ok for Belgrade.
Distance to city center some 3 - 5 Euro by taxi.
Room size is ok, TV works. Personal is friendly. Bathroom has broken parts in shower and broken light. Enough hot water. Not 100% clean, but acceptable.
However, breakfast is *excellent*!
Price 60 Euro for two people.
Would come again.

(Important !!!
For those how need a taxi at the airport, do the following:
*Do not accept any taxi offerings !!!!* (rip off by illegal taxis protected by airport police !)
1.) Turn left at the very exit of the customs
2.) Take the stairs up direction departures
2b.) If heavy loaded, take the elevator hidden in the bottom of the bar situated left after exit the customs (if you think you are wrong, then you are right, and yes, it is a public elevator and it works ;-) )
3.) Once at the departure level, just go out and take a taxi with the official sign on the roof.
Some taxi associations: Pink, Naxis, Maxis, Lux, Beogradski, Plavi, Alpha, Zuti.
Price to Novi Beograd "around" 7-8 Euros, Center 10 Euros, Hotel N 15 Euros, Other side of Belgrade 20 Euro. (1 Euro start and 60 cents per km)
