Sean and Mary's place was just right for us. It was a lovely big, bright room (just as shown in the photos), attached to the main house but with a separate entrance. There was good storage space for clothes etc and a large, clean bathroom with walk-in shower. It was a lovely room to return to.
Mary laid out breakfast each morning for us in the kitchen, which we appreciated. She joined us a couple of mornings to hear about our plans or give advice for where to go, where to eat - and how to pronounce some of the Irish names! We also enjoyed the coffee machine in the bedroom.
Monkstown is a very pleasant town with good eating places just around the corner from the apartment. It was also very handy for the wedding we were going to in Dun Laoghaire. The DART station is two minutes from the apartment and was handy for getting into Dublin as well as going to Dalkey for dinner one night. Being outside of the city, it was easy for us to travel to the south in our hire car for exploring.
The apartment is down a small lane. There was a parking space but we did need to take care to park hard up against the wall to keep the road access clear. Although potentially difficult to find, Mary's clear instructions meant we got there without trouble and, in fact, the apartment is not far off the main road.
All in all, this was ideal for what we wanted and we would be happy to recommend it.
