It was a great stay! The apartment is located very centrally, close to many bars restaurants and cafés. It's also clean and seemed pretty newly furnished. I also liked that the flat's door is very safe. My friend was doing Airbnb for the first time and is already a member.
There is a pub outside, that can get loud so I recommend bringing ear plugs.
All in all a superb stay and I'm already looking forward going back to this place next year.
