During 17-12-2006 and 31-12-2006 i visited Tehran, my traveling pictures are published to my PicasaWeb album:
I stayed at Tehran Grand Hotel (Hotel Reservation per Fax: +9821-8713857), which is in Tehran central, you could call for Taxi Service in Hotel or take a Taxi by yourself or go by Metro (Motahari street former Takhte Tavoos street).
I visited Tarjrish Bazar, i recoomenad Sharaf-ol-eslami Restaurant for persian food.
Nivaran Palace is one of my favorites too, you could visit Niavaran Park and Chel-cheleh Restaurant too, which is near to Nivaran Palace.
Golestan Palace near to Toop Khune place is very nice.
The current € exchange was 1212 toman (1 toman = 10 Rial)
I recommend to visit Isfahan and Shiraz too, please keep in mind that domestic flights could have delay.
For iranian confection and nuts, visit Tavazo store at Vali-asr street.
Iranian films and music could be found at "Moaseseye Rasanehaye Tasviri" at Vali-asr street.
