we loved our stay on grassmarket - a stones throw from the castle and royal mile, only a ten minute walk down advocates close to new town and waverley station and really close to greyfriars kirkyard.
grassmarket itself is full of pubs and places to eat - highly recommend Hula that you can see out of the window of the apartment for breakfast, and the roof terrace at cold town house at the opposite end of grassmarket for cocktails and lunch. location is fantastic.
west bow is quite lively friday and saturday nights but as the bedroom is on the back of the apartment we barely heard anything once we were tucked up and the doors were shut.
the apartment itself was a lovely little place with an amazing view down grassmarket through georgina sash windows complete with wooden shutters. kitchen was well equipped and already stocked with tea, coffee and sugar (a shop is 30 seconds from the apartment for milk so really convenient). very clean and decorated really nicely - the harry potter hints are all over the place but it’s not too in your face, so my non-HP partner still loved the decor even without the background knowledge!
place was easy to find thanks to the welcome booklet that we received via dm the day before we arrived - the only problem we had was we couldn’t find the key box but barry immediately responded and we were in the apartment within a minute of sending the first message.
overall we loved our stay here and would definitely book again.
