Had a lovely time staying at this property. We had a large group of 16 people, and it worked out perfectly. The house is definitely big enough to comfortably house a group of that size, and has enough bathrooms and living space that we didn't feel cramped.
The hotel check in is a bit of a walk from the actual property, which should be taken into consideration if you have accessibility needs and would struggle with walking up hills etc. However, the staff were kind enough to hold our bags at reception until check in time, and to carry them over for us in a mini van at check in time, which made things easier.
The beds are all single beds, which could be useful for groups without many couples. A cleaning team came in the second morning to change bins and towels, which was nice. The staff were also very accommodating when we left a small item behind, and posted it back to us.
The location is also good, with Cobh town centre, a Centra, and some takeaways a 5 minute walk away. There is also a small stoney beach 5-10 minutes walk away.
Would recommend you bring your own toiletries if you have a large group, as there were very small shower gel etc bottles. The house was also missing hand soap and some basics like salt and pepper, but there is a shop very nearby.
Overall a lovely place to stay, and very friendly and helpful staff. Would recommend :)
