My family and I spent 3 weeks at Kate´s place. First it important to say that contacting her was very easy before and during our stay. She replied all the messages very quickly and nicely. Picking up and returning keys was also very easy.
The apartment is in a residential area, but within 15 minute walking you can get to Temple Bar, Dublinia and other touristic attractions. This distance worked well for us since we had quite a long time in Dublin and I had to go to Trinity everyday (20-25 min walking) for work.
The apartment is big, with a spacious living room integrated with a kitchen. The bathroom is also very big. There are 2 bedrooms with double beds and wardrobes.
Kate left us the basics for cooking (more than the basic to be fair) and washing our clothes. She also left some bathroom goods, such as soap, toothpaste and other.
The apartment was clean, so were the linens and towels.
We had great days there! I would recommend it if you are visiting Dublin!
