Gavin's place is a great deal. Its location on the river in Temple Bar (on Bachelors Walk) is ideal for being in the center of things and navigating the city. It's not only surrounded by many restaurants, pubs, and shops, but it's within very close walking distance of key sites, like Trinity College.
As for the flat itself, it's nice, clean, modern, has great amenities (such as the fast wifi), and is spacious. There was plenty of room for the three of us (two adults and a baby). The living room has a large window that opens right onto the street by the river, which is picturesque and fun.
Gavin himself couldn't have been kinder or more helpful to us. He was accommodating when we got lost on our way there and checked in a bit late. He walked with me to find my parked car and help me locate our rented parking space. We had issues with the local SIM card we'd bought the week before, which meant that we weren't able to use our phone to open the parking gate; however, Gavin was nice enough to be on call for whenever we needed to leave, and he opened the gate for us. He was a great host, very helpful, and kind.
