I stayed in several AirBnB’s in June of 2016 and was very pleased with the results. Except for Galway, all were rooms or sections of the hosts’ actual dwelling place.
I checked each host’s online reviews and only booked with those who had lots of positive comments. There were no problems with cancellations or communication. Every place lived up to or exceeded my expectations based on how they were described on AirBnB.
With two exceptions, the hosts I visited were doing it partly for the interaction with guests in addition to the money. The two exceptions were still very friendly and helpful, but after brief interactions and the check in, they weren’t around as much. The others were available at times for conversation, especially at breakfast. In Dublin, my host had a friend over to watch Ireland play in the World Cup, and I had a long and wide ranging conversation with them after the match. Meeting several wonderful local residents and discussing a variety of subjects with them was a highlight of the trip.
The two exceptions still provided an affordable and adequate place to stay in the more expensive cities.
I also stayed in guesthouses and regular B&B’s, which were all good as well. Although I booked my sites in advance (from late March through May), I saw lots of B&B’s with vacancy signs in most places I visited. Except for small villages or if you’re arriving during a major event, you should be able to find an alternate if an AirBnB host cancelled.
It is a good idea to book ahead for some of the more popular places (that includes guest houses as well).
Here’s another site I used when I couldn’t find an AirBnB I liked:
