we spent an additional night in the sadaf due to both the wonderful atmosphere in the city and the very obliging service in the sadaf hotel. the rooms are quite spacious for a good price and in addition to a pair of slippers and warm towels you also have your own prayer rug :-) a big plus is also the location as the famous imam square is just a 5 minutes walk away. we stayed there in summer and had a fantastic time, watching the european football championships in persian ("lehmon!", ''bollock!", "lohm!" :-). though a colleague who stayed there in winter complained about a disfunctional air condition which bestowed upon him a severe cold.
