Tina's apartment is spacious and quiet, with a clean, contemporary design. The bed was big and relatively comfortable (compared to most motel/hotel beds I've had to sleep on). The windows provide plenty of natural light during the day and provided good cooling air circulation during my stay, which happened to coincide with a bit of a heat wave. The bathroom and shower are beautiful, with good hot water (on an easy-to-use timer) and great water pressure. The kitchen also looks great, though I admit I did not make much use of it beyond storing things in the fridge.
The building was actually quieter than I expected; neighbors were certainly present, but I rarely heard them. There's a little deck that provides a nice place to sit outside, and the open living room has a couple very comfortable couches if that's more your style. As the listing mentions, there is no TV, but the WiFi was more than enough for me to stream Netflix on my laptop.
There's a nice little convenient store just outside the main entrance which provided basic amenities, plus simple options for breakfast and lunch. The buses into the city are about a 10 minute walk away, depending on your pace, and were fairly frequent. The ride in to the Trinity College area was about 20 minutes. Taking a taxi is also an option, but was a bit pricey due to the distance. There are also buses that will take you to the coast, where you can take the DART to various other interesting suburbs.
Overall, this was a great place to stay. It's away from the noise of the city, providing a quiet, calm place to recharge, but close enough to the city to be able to sight-see all day and explore the nightlife well in the evening. I would definitely return if it were available next time I'm in Dublin!
