We stayed at Lens place for three nights and we had a really nice time. The flat is located in a beautiful part of Dublin with a lot of nice café's and pubs maybe 5-10 min walk down the road. There is a tram station just 3 minutes away and it takes you to O'Connel Bridge in under 10 minutes. You can also walk to Temple Bar in 15-20 minutes.
Lens offers self-check in which is great when you don't know exactly when you will be arriving. He is very fast in responding and when I had a little problem he called me back immediately.
I would definitely recommend staying here and I would like to come back one day.
