Marie and her husband are super nice and welcoming people. The room is very big and the whole house is really nice. There are two bathrooms, so you can always have one to use in case the other one is occupied. The view from the room is very suggestive and the bed is really comfy. I've been at their place in November and I also have to say that the house was very warm, luckily, cause outside it wasn't! Moreover the house is very close to metro stations Frankfurter Allee and Ostkreuz that are very well linked to the city centre, to the airport and to other interesting areas placed southern and eastern from city centre. The house is also very close to Boxhagener Platz which is a really nice area to pass through and to go eating, giving real Berlin vibes that are harder to feel downtown.
Highly recommended!
