This apartment is in an excellent location only 5 mins walk from the Old Town Square, yet it's really quiet and tucked away. I recommend it if you fancy something different to all the standardised Ikea flats that seem to be available. It's in a beautiful old building - the photos are a good representation. It was also cosy and warm in the cold weather. The kitchen is reasonably well-equipped and there were candles scattered all over the apartment which we made liberal use of. I thought this was a nice touch. Worth noting that although the bathroom is modern, clean and very nice, there isn't a proper stand up shower so you do have to sit in the bath and hold the hose over you.
I also recommend the James Joyce pub over the road. Not as cheap as some but the beer was great and the service fantastic.
