We were very happy with our stay at Mary's house. She was lightning quick at communication from start to finish and dealt with any questions during our stay almost immediately by email. She was also very flexible with our check in and check out which really helped us. The house is cosy and warm (our stay coincided with a particularly arctic spell of wintery weather) and we especially liked the gas fire in the conservatory. This is a genuine lived-in home so comes with everything you could possibly need (and a few quirks!), including a well-stocked kitchen. It's a big property and was well able to soak up our party of 6 (including a toddler and a baby), although it's not toddler proof so you would need to bring your own stair gate, high chair, etc and make a few temporary adjustments around the place. If anything there was an oversupply of blankets and towels but I'm not complaining!! And you'll never run out of wine clean wine glasses in Mary's kitchen!
The location is great as we wanted to be near to the airport and also have the beach for fresh-air walks etc. Malahide village and castle are nearby and there are excellent public transport links in the neighbourhood. We found the leisure centre (and its excellent playground( across the street to be great for the kids and we also enjoyed several nearby pubs and restaurants. Dunnes Stores, which is an excellent supermarket with loads of hot and fresh foods available, is less than 10 mins walk. The beach is 15 mins walk.
We were using the property as a base for returning to Dublin to visit family and friends, it's practical and homely. Lovely back garden too.
