We stayed in this great apartment in August 2018. It is located in the Old Jewish Quarter right above the James Joyce Pub. The apartment is on the sixth and top floor, so you have to walk up 5 flights. My kids scampered up, but I moved a little more slowly. The building stairwell has lovely high ceilings and it was fun being on the top level. The apartment had skylights and you could see the tops of the historic buildings from them. It also had great AC--a real treat since it was quite hot when we went. We were greeted by Dominika, who was very helpful and friendly, and the owner was always prompt and helpful in replying to my texts. The apartment has everything you need, including a combo washer/dryer. (FYI, the dryer takes 3 hours to dry, so plan ahead). The beds were comfortable and there was plenty of hot water. The location was great--no more than a 10-minute walk to anywhere in the Old Town. We took a cab from the train station--beware of the guys not parked in the queue directly in front of the station. I saw a cab driver parked to the left of the hallway and asked him for a lift (I was tired and disoriented, which I think they bet on). He tried to charge us $40 for what should have been a $10 ride. You can easily walk from the station (16 minutes, but it's a slog if you have luggage). Also, when you go to change money, DO NOT use Western Union. They charge a huge commission and try to trick you by offering a higher exchange rate. They tried to charge me 17% and charged the old man before me 28%! Go to a bank or one of the places where they say "0% Commission," and be sure to ask what they will give you back first. Take the time to do the math before you agree (check the exchange rate online first). Also, try to bring a few Krona with you, some places take Euros, but not all, and no one takes dollars.
All in all a great trip and a great place to stay! Having the pub below felt like an added bonus--good food and great outdoor tables, and a nice respite from the throngs of tourists at the other restaurants.
