Petrea's place is lovely. She has such a lovely collection of books --just for that I can go there again!
What will attract you most is, of course, her location. Right on Holyrood park and within walking distance of the royal mile, you don't need a car once you are at her place.
Parking at her place is a nightmare though. If you are coming by car, then be prepared to park some distance away, which can be daunting if you are new to the city.
Her place is warm, cosy and very comfortable. Her kitchen has lovely lighting and puts you in a very good mood right away.
