The good: It's very clean, immaculate even.
How many the place sleeps overall: The listing says the place is a squeeze for more than 8. That's true, but that's a little like asking how many clowns can fit in a clown car. I once let 12 friends in from Boston crash on the floor of my 750sf Brooklyn apartment for a night. The fact that it was doable was complicated only by the fact that there was just one bathroom--as is the case here. How many fit comfortably here? It depends.
The noteworthy: over the hot summer weekend that we were there, there was a constant flow of feet up and down the BR fire escape from other building guests doing some afterpartying, nothing out of the ordinary for a city apartment located directly across the street from a pub featuring loud music late into the night.
Miscellaneous: To sleep 6 in the LR, you need to move one of the sofa beds depicted in the photo so that it can open without hitting the sofa bed across from it. Instead of 4 bunk beds in the bedroom, you're looking at a queen bed and two bunk beds in there. The washer and dryer are not in the apartment itself but rather, on the landing in a closet across the hall from a neighboring apartment unit.
Communication with host: Kevin responded immediately to our texts. He texted us a few days before to confirm our arrival time, and told us to text him following our arrival at Dublin Airport. Once we did that, he texted us the keypad code to enter the building.
