Despite the "so many" restrictions, the hotel hosts every night a wedding party in the wedding hall, and if one stays in the lobby, you will see the Creme de La Creme of Tehran coming and going.
Buffet breakfast is available, and is good as well.
WC needs some more upgrading though
TV shows only Iranian channels in Persian (Farsi) and One Arabic language channel (Iranian gov channel) + BBC world in English.
All in all it is ok.
Price a bit on the high side, but it is the best you can get in Tehran.
Don't miss the restaurant.
