my family of 6 stayed at Karen's accommodation for 6 days and it was absolutely perfect for us! everyone had their own space. it was only a 5 minute walk for public transportation. as well as a nice amount of places to eat or pick up food. she has everything set up and check-in was a breeze.
there are 2 flights of stairs you have to battle your way up but for the space it was worth it!
I'd recommend this house for any group trip!
