We had a very nice stay in Tia's appartment. It was as nice and well equiped as described and we all feel like at home. The two bathrooms are big and confortable (a must for a 6 persons family). The appartment is really accessible (ground floor) and was easy to live for our daughter which is in a rolling chair.
The place is ideal to discover Berlin easily with the U Bahn. The Plannufer U Bahn station is equiped with an elevator.
The neighborough is very plaisant, lot of shops and restaurants near the appartment and a great ice cream shop. We also enjoyed the public swimming pool.
Tia was very helpful to prepare our stay and her friend Eugenia welcomed us and explained everything as Tia was travelling when we arrived. For sure we recommend Tia's appartement !
