Ella was very nice and responsive to the problems we had, of which the biggest issue was that we had only one key for 6 people because the people who stayed before us had taken the second key. So, this wasn't his fault but it was unfortunate.
The main problem for us was the sofa bed in the living room. It was so uncomfortable to sleep on that we did not feel that the person who slept there should pay her share of the accommodations.
The apartment is in a great neighborhood which we enjoyed spending time in.
