Hotel Ametystvs?

"Though little pricey for the location -- a quiet backstreet about 5 blocks from námestí Míru -- the Hotel Ametyst is spotless and decorated in a warm contemporary style." Full review

"Fine, modern townhouse-style hotel with air-conditioned rooms, all with private bath or shower and Internet access."

"Ametyst is an upper-middle-range, boutique hotel in a quiet, residential part of Prague... the free hot and cold breakfast buffet has a wide range of options." Full review

"The polished Ametyst straddles the line between boutique and hotel, with just enough style points... to put it in the boutique camp." Full review
