My boyfriend and I spent 4 nights (Thursday - Monday) at Ben's place and it was a great stay - everything just worked out fine.
We got a warm welcome by Ben's mother Sally who showed us everything and was very friendly. The bedroom and the bathroom were clean and provided everything we needed: towels, hairdyer, shower gel, shampoo, tea, milk, candy and a small fridge.
The neighbourhood of the house is really nice, we felt safe all the time because it is a pretty area with some pubs, restaurants and cafés. The bus stops right in front of the house, but you can also reach the city centre via St. Stephen's Green walking about 15 minutes.
We definitely would stay there again!
