We had a wonderful stay here, the apartment is in a beautiful building and Karin has decorated it in excellent taste, making great use of the space so it feels a lot bigger than a studio. Karin was very welcoming and little touches such as breakfast ingredients (homemade granola, yoghurt, fruit, soda bread, good coffee) and shower gel, shampoo etc were very welcome! She also gave lots of handy local recommendations and checked everything was to our satistfaction. The kitchen is very well equipped and we loved the log fire, the gallery bedroom is cosy and comfortable. All was clean and tidy and the street isn't noisy at night. While Mountjoy square isn't one of the most fashionable locations in town, taxis are so prolific and cheap (our longest wait was just under 60 seconds) that we just hopped in a cab to go out in the evening and did the short walk into town during the day.
Would definitely recommend - if in Dublin we will certainly want to stay here again!
