What we liked: very clean, lots of light, location away from heavy tourist traffic yet easy walk to all key sights, spacious, host facilitated set price taxi from airport for fair price.
Things to bear in mind: apt directly above a pub and... another bar in the building which means lots of patron noise until very late (1 and 2 am). Apt layout maximizes beds, but not privacy (twin + queen directly adjacent to kitchen, another queen next to living room couch/tv). Apt outfitted very sparingly (no paper towels, tissues, extra toilet paper, shampoo, coffee/tea, tourist info, shelf in shower for shampoo/soap or place to set toiletries in bathroom) and bed sheets were of poor quality (although host promptly remedied sheets upon request).
