We had a great stay at Caroline's place. It's stylish and has everything you need.
The location is very central in the old town so perfect for exploring the city and within easy walks of great restaurants and bars.
As others have mentioned due to its central location near clubs and pubs it can be a bit noisy late at night. If you're a light sleeper you should bear this in mind. It didn't bother us though and we really enjoyed our stay.
