We had a great stay in Ulla's apartment. The flat is spacious and comfortable and perfect for a large group. It's well stocked and was great for us travelling with our toddler as a travel cot and high chair were provided - there were even some toys to keep her entertained.
The location is fantastic with easy access to transport to get around Berlin.
The hosts were friendly, helpful, and easy to communicate with. They helped us with taxis and local information and made our stay easy and trouble free. Overall we had a lovely time and wouldn't hesitate to go back.
