The level of communication from Paul, location and feeling safe are all top notch. Paul replies quickly, gives clear instructions, and is a helpful resource of the city.
The apartment is a 10 minute walk to Temple Bar Area, Grafton Street for shopping, but also on the same block as some really neat bars and restaurants that aren't near the tourist areas. We stayed for 4 nights with two people, and while we weren't completely on top of each other, it was a cozy fit.
Paul is kind to leave a coffee machine, teas, coffee for a quick morning cup before you start your day. However, there is no kitchen in the apartment, that we saw, so don't plan to pick up groceries to make your own meals.
The downsides to this apartment is the bathroom. You'll see this on other reviews, but the bathroom is outdated and needs some work. You share this bathroom with other guests and Paul, which is fine but can sometimes be problematic in the morning when everyone is trying to get out the door.
Overall a good stay for the price.
