Mevina's place was a good choice for my stay in Dublin. The room was very clean and warm and she added some details like a wee tea/coffee corner in the room. Communication with her was so easy both by phone messages and emails.
The house is in a quiet area just besides the Guinness Storehouse and close to Phoenix Park. You could go walking to the city center in 30 minutes.
However, apparently the boiler takes over an hour to heat up the water so if you want to take a shower, you should bear that in mind.
Apart from that, my one night stay was fine and both Mevina and her kid were very nice.
