hotel adria was great! the rooms were small...but that's prague for you! it's a 4 star i think. the triton restaurant is in the hotel which is nice. it's right in town close to charles bridge, old town square, prague castle.
FH's brother lives in prague with his wife. we went to visit them last summer and stayed in prague and then went to vienna. let me know if you want any suggestions of things to do. i know of a fun beer garden, museums, etc. i'm in close contact with them, so i could always ask questions as well for you.
you helped me with flowers, now maybe i can help you with prague!
