We were two families (4 parents, 4 teens, 2 dogs) staying for a week in June.
Mike's place is fabulous and perfect some someone travelling with a pet (or two). There is a fantastic kitchen / dining area which is really the heart of the house. This common space offers lovely views towards the Iveragh peninsula in the distance. The two families hung out there most of the time rather than the living room which did not have enough furniture for all of us (also we wanted to keep the pets out).
The kitchen is generally well stocked but do bring along anything specialized you might need if you plan to cook a lot. The house is perfect for pets because it is easy to clean and spacious just about everywhere. The bedrooms are spacious and clean with good bathrooms.
Mike is a great host, who is easy to deal with and very responsive. For example when we had issue with the internet (two of us were remote working during our stay). Mike turned up the next day with an extra hotspot. However I would not have high expectations for internet access - it is not the best. This is not Mike's fault, it is the location.
The location is perfect for getting away from it all. Amazing views from the front of the house. It is hidden near the end of a quiet little boreen with only occasional farm traffic, a nearby sheep and cattle farmer whose animals live in the fields around you.
A 20 minute walk gets you to a beach or (different direction) a nearby pub (which was closed due to Covid during our stay). A 5 minute walk allows you to join the Beara way - where another 1hr/20min will see you arriving in the lovely little village of Allihies for a pub lunch and a nearby sandy beach. A 10-15 minute drive brings you to the lovely fishing port of Castletownbere.
One thing to consider however is that parts of the Beara way are not pet friendly. There are signs which indirectly threaten that your dog will be shot (not clear if this this applies even if on a lead in some cases). I can understand why farmers might be frustrated with irresponsible owners letting dogs off leash near farm animals - but the signs with their insidious threats in some cases are not an appropriate way to deal with it.
