We stayed at Helena's place for 5 nights and enjoyed our stay very much.
We didn't meet Helena in person. Her husband was there to welcome us and explained every detail. He was very friendly and helpful. We felt home straight away!
The description and the pictures were accurate.
Breakfast was kept in the fridge for us and we were very independent since the rooms are separate from their living area.
Messe Berlin is 20 mins walking distance away. The cost of a taxi: EUR 10-12
There is no restaurants close by since it's a residential area but there is a stove and oven available at any time.
We highly recommend this place. specially for people who like to walk :-)
I would definitely stay at Helena's House again.
