I stayed with Grainne for two months this past summer. Some things about the place were as lovely as she describes them in the listing. The backyard is beautiful, the shower and toilet are a treat, and the location is easy and undemanding.
But the space had a pile of irritating oversights, especially for a longterm guest, which the description doesn't make clear. For example, the description does not say that there is no AC in the house and the guest does not control the climate in the apartment. For me this meant a sweaty summer. Though the basement is cooler than an attic would be, it is a basement and it is moist. (There is a dehumidifier that needs to be emptied twice a day.) I bought myself a cooling tower and still spent some days sitting in the shower to cool off. The description also does not say that the refrigerator is dorm-sized and has only a tiny freezer, not even big enough for an ice tray. I would have liked to have had a pint of ice cream in the freezer or not needed to go to the grocery twice a week because the fridge is so small! The range looks good, but the burners need to be cleaned or repaired. Some wouldn't ignite at all, others the flame was so low it took an hour to boil water. There is also no dishwasher or microwave and I had to bring my own coffeemaker. I spent about $250 to make the space more livable by putting in a desk and chair, a few extra lamps, the air cooling tower, etc. I wish I could have bought myself a new bed since the mattress was old and mismatched to the headboard, so the pillows constantly slipped into the gap.
The other issue is that the space does not feel as private as I had expected and hoped it would. The noise from upstairs is very audible in the basement. I could hear her son practice violin. Some days I could hear snippets of conversations and so of course I worried that sound was traveling up too. The door between the basement and the house has no lock from the basement side and so I had to trust that no one would come down. The shared laundry space was actually less of a problem and Grainne always made sure to tell me when she would be there.

I have stayed at many short-term rentals and I don't expect them to be like hotels, but I must add that Grainne's attitude was not always professional. I thought a lot about it before posting this. I really don't like saying things that are potentially hurtful. It seems worth it, though, to let other people know. I hope the space does improve. It could be great.
