This apartment is located centrally enough but the price is extremely high compared to the rest of the rental market and the apartment's furnishing doesn't make up for it. The furniture is of the basic-most type and there were a few things not working (a laundry machine but no drying rack or tumble drier; light bulbs in the kitchen and the bathroom having gone off before we arrived; hardly enough pressure on the shower to wash shampoo out of the hair -- for some reason there are two separate shower heads, neither of which has sufficient pressure; the doesn't work but the grill does if you can figure out the temperature settings with the labelling having gone; a picture had come off the wall and was lying on the bed; etc.). Paul was very responsive when we inquired about the first couple of these and send someone (who was very friendly and competent, in fairness). As we discovered more things that weren't working it felt too much of a hassle to contact him for every single thing that needed fixing and making time so the person could come for repairs. At this price, at a minimum, things should be working without having to ask about getting everything fixed individually.
The area is ok and fairly central, often described as 'rough' by locals. I'm still not sure what this means exactly but we experienced a noticeable density of drunk adults at all times of day and weekdays, including inside the building, and a lot of noise during the night: mostly car alarms and crackers/fireworks, once car windows got smashed in by some kids, as did one of the street level front doors, a few doors down from the house. The bedrooms are street-facing, the windows don't close well and are single-glazed. I ended up using earplugs every night. There are some small supermarkets in the area but most of them aren't worth the trip as they stock very little (if you're vegetarian don't even bother with the Spars). Lidl on Moore Street is the closest better-stocked and better-priced supermarket we found. The two Dublin Bike locations in front of the house are quite useful for getting around.
Overall, this accommodation seems well overpriced: we booked it because we were desperate for accommodation and didn't have have any other options for short-term rental due to the housing squeeze in Dublin. I wouldn't recommend it under different circumstances.
