David and his wife were just great. They were super responsive to any question or need and were patient as I asked more than a few questions our first two days. They also addressed any concern I had very quickly (e.g., my daughter is cold natured, and they quickly adjusted the temperature higher for us). Check-in was also easy. They were great hosts.
As for the space, a few things. The washer and dryer were separate (!!) and easy to use (instead of those combined washer-dryer units that confound me as an American, and never seem to dry). I thought this was important to point out, especially if you are there with quite a few people with lots of stuff to wash and dry.
The duvets were fluffy and warm, towels plentiful, and the space was big enough for our two teenagers to find privacy but then still hang out with us. There was also Netflix.
The location is incredibly quiet (except for the seagulls in the morning, but that can't be helped). It's tucked back into a tinier street off of an already tiny street and you wouldn't believe you're in a big city.
As information, the master, kitchen, living room and one bathroom are upstairs, and the two other bathrooms are downstairs. There's a little courtyard out front and then a wall with a door that blocks that all off for privacy (though we were there in November, so didn't hang out in that space).
Location-wise, it was for us a 20-22ish minute walk (but easy) to major stuff (like Dublin Castle and Trinity), and maybe 7-8 minutes to good grocery stores and pubs.
Would absolutely stay here again. Thanks David, for being such a great host.
