Alberts place is incredible. He is so attentive to your needs. The place to me was more beautiful than the pictures. Alberts even took the time to welcome me with a box of cookies, juice and water. The shelves are very stocked up with item for cooking and best ever for supply of toiletries.
Everything is decorated with a fine touch. Even gummy bears were put on the pillows and new towels.
One thing to keep in mind is that if you do need an elevator, this will not be a good location for you. I enjoyed the walks and the 4 levels up and down on the steps were no issue for me. If you don't mind steps, Alberts's place it the most perfect place in all Berlin.
