My family and I stayed at Senan's place for a week while visiting Ireland and the entire stay was fantastic. The place was clean, access to the key upon arrival was simple and easy, and the location was great. The welcome packet and information left was really helpful and above and beyond what I have experienced elsewhere. The local cafe's / pubs and restaurants were really good as well if you do not feel like walking to and from the city centre (which I felt safe doing even in the wee hours of the morning). I absolutely recommend staying here if visiting Dublin.
