Helena is a delightful host. The house was spotlessly clean. While I didn't have an en suite bathroom, there was a toilet and wash hand basin right beside my room, and a bathroom upstairs with electric shower. My room overlooked the rear garden and had a comfortable bed and lots of storage space, including a small desk and chair. I was able to use the kitchen and had a parking space off the road.
The location was perfect. The 14 bus stops right outside. The Dundrum Shopping centre is 10 minutes walk away and the Luas to central Dublin is another 5 minutes further on. The Dundrum centre has some very good restaurants which are open in the day and evening.
The Luas takes 15 minutes to St Stephen's Green.
