I stayed in this apartment for 4 nights in August with my 1.5yr old son and husband. It was excellent, and we would love to come back and stay here again! Claus was very welcoming, and made sure we had everything we needed.
The location was very central and we were able to walk to all the main sights.
I would definitely recommend this apartment to anyone- it would suit a couple traveling, and is also excellent for families as there are lots of toys to play with as well as access to a safe yard with a small playground.
