I really enjoyed my stay at this apartment. It was exactly as shown on the pics and described online. Since I was working remotely I spent a lot of time there and everything worked well. Great location very close to the city centre but still quiet enough. I walked pretty much everywhere by foot. It's close to most sightseeing highlights as well as to temple bar or many other pubs and nightlife spots, shops and Restaurants/ Chippers.
I was never disturbed or annoyed my the noises but be aware that you'll hear the church bells (literally just across the street) and also street noise since it is ground floor level. There are blinds at all windows and dark curtains so I never felt like people could see in. Also I felt really safe at all times, even walking home late at night.
It's a lovely apartment, bright and cozy and spacious for a single person (even for a couple totally fine I'd say). I'd definitely stay there again.
