I highly recommend to stay at Sóllons place, especially because he's such a lovely, hospitable person. The clean and cozy place is also very close to the city center of Dublin, sights like Temple Bar, Trinity College, Camden Street etc. are just a walk away.
Sóllon made a lot of effort to make my stay as enjoyable as possible. He changed shifts to enable me a later check-in and to welcome me personally. He also bought food for breakfast and was always helpful with information. He always made sure that I feel comfortable. So there's absolutely nothing I can complain about.
It was my first time booking a accommodation via airbnb and Sóllon made it a very positive and special experience. The only bad thing was that I couldn't spend more time with him :)
