This is a good option for a short stay in central Westport.
The bed was very comfortable, and the room was bright, super-clean and had a nice bathroom.
At the time of year we went it was good value compared with hotels and other airbnbs in the area.
It was great to be able to walk down into town and be at cafes, pubs and restaurants within 5 minutes. Recommended - Moran's for Guinness, This Must Be the Place for coffee and breakfast, and Savoir Fare for lunches, snacks (and really good coffee too).
The on-street parking was good value (3 euros for 24 hours) and we could always find somewhere very nearby.
It's worth noting that there was a certain amount of traffic noise in the morning but it didn't trouble us.
All the check in/check out arrangements worked well and very helpful communication from the hosts. It was nice to very briefly meet the hosts.
