Lotte is a great host. Although we didn't meet her, she was so helpful - replying within 5-15 minutes to any email. She gave us several options to set up the sleeping arrangements for our 2 year old daughter, and was willing to move things around after we arrived as well if needed!
She also pointed out several things going on in the area that we wouldn't have known about otherwise.
The apartment itself is lovely, and the kids playroom was great for our daughter!
The only downside I would say is that the apartment is in quite a lively area so Friday and Saturday nights were quite noisy. Other than that, this was a great place to stay!
