I was there for a 4-day conference at Hynes Convention Center. The apartment was clean and very well located, just a 3 min walk to the the convention center. Lots of restaurants and grocery store nearby. A local resident told me about the "Star groceries" which is just a 5-7 min walk from the apartment. There I was able to find everything I needed for the breakfast and snack during my stay.
The apartment itself is very small - smaller than it looks in the pictures. It was perfect for me alone. But if you are booking this for 2 people, this will be very tight.
The kitchen had nothing more than 1 pot and about 4 each of plates, cups and cutlery. So you cannot plan on doing any cooking. It did have a coffee pot, toaster, and microwave. However, there was no coffee, sugar or coffee pot filters. For that matter the apartment had no spices - not even salt or pepper or cooking oil. Basically the only thing you can do in the kitchen is warm up some left over food in the microwave or toast some bread.
The check-in time is 4 pm - later than any AirBnB I have stayed at. So plan accordingly.
