I recommend this place.
Because of the price location and the use of the house.
Price
Look at hostel prices. Dublin went crazy with that.
Location
I found that Declan's place is located in a super fancy area. You will enjoy nice surroundings. Plus, one only need to walk 20 min to the main attractions.
Use of the house
One has acces to the kitchen, bathroom and sofa. We found the sofa comfortable the first two days but then you missed a bed. Again you have the other spaces.
what should you expect?
Declan will be waiting for your arrival to give you his spre keys and a control remote. Then you won't notice his there. he will be studying in his room. Next days, he will ask how's everything going and the last day you will discuss how to give him back the keys.
