Lauren and Chris were great hosts - very friendly and helpful at check-in, and pretty much hands off during the rest of our stay. Lauren responded to all of my messages promptly and made sure we had everything they needed.
The apartment/flat itself was amazing! It almost felt like we were staying in a hotel suite. Towels and shampoo/conditioner/body wash were provided, and the kitchen was fully stocked with dishes, glasses, and utensils in case we wanted to cook anything. There was also enough coffee and tea there for five nights shared between six people. We also really appreciated the Apple TV in the main room. Basically, all of your bases will be covered in this apartment.
A couple small things that you should know going in: there is only one bathroom in the apartment, so if your group is on the larger side, you'll need to be coordinated in order to start your day as quickly as possible. Also, Lauren and Chris have small children, and we could hear them running around the house on the floor above the apartment. It wasn't really an issue for us because we were up early and back late most days, but I think it's worth mentioning.
All in all, we were very happy with our stay! I'd wholeheartedly recommend Lauren and Chris's place.
