My stay with Monica and Yvonne was absolutely ideal for my quick (but really great!) stay in Berlin. Lovely hosts, very friendly and welcoming family. The room was the perfect size for me, with cool art on the walls and a comfy bed, good wi-fi, and the bathroom was clean & functional, with really good shower water pressure.
The apartment is located on the top floor of a large complex and had a great view overlooking the city. Secure building which was nice. Had my own entrance with a key and my own bathroom, and although it's not completely private and separate, the hosts mainly stay in their own space and you in yours, in case that is an issue for anyone.
Absolutely perfect location for getting around the city via transit, it is directly across from Alexanderplatz, and lots of bus stops, including one for the TXL bus to/from Tegel airport. More of a touristy area but doesn't matter much as you can quickly get anywhere else you want to go if you don't want to stick around.

I will definitely come back on my next visit, great deal and friendly hosts.
