We stayed two nights at Ana's and it was a great experience. Ana was very helpful from the time I booked until we left. She very kindly had bread, butter and orange juice stocked for us which was more than expected, and she had bus and luas directions printed for getting to the city centre.
The apartment was very comfortable and clean and the kitchen was well stocked with necessary appliances if required. Wifi available also.
The location is great, right next to UCD in a quiet area and it was great to have free parking available. We got the luas to the city centre both days, it was just a ten minute walk to the stop and got a relatively cheap taxi back to the apartment.
Overall, based on quality and price, I think it would be hard to find better value anywhere in Dublin.
