This place it's amazing.
It's in a safe and beautiful building, I was in third floor and the stairs were fine you can carry your luggage with no problem. The apartment it's perfect for 6 guests. Full equipped kitchen, dining room for six. Spacious rooms with confortable beds. One bathroom with all you may need. Everything was clean and organized.
Gill is an amazing host, she showed us the place and explain everything. Ease to contact by email and always had an immediate answer. The appartement it's located really close the temple bar so you can walk around all day and come back easily.
We are in love with Dublin and with this apartment. Totally recommend.
