Would highly recommend a stay at Pier's pad! My partner and I went for an anniversary weekend to Edinburgh and Pier's place was just perfect.
Excellent location (not too close to town center, but easily walkable), high standard of décor/cleanliness and comfort, and just the little added lovelies that Pier included made our weekend perfect.
Definitely listen to the recommendation about Café Renroc opposite the apartment, had a lush breakfast & coffee here on our first morning.
