TOP SPOT!
Quite close to some of the essential Berlin's spots (~15 minutes to Branderburg Gate); very good transport (trams, buses); markets, liqour shops and some fast foods near it as well.
TOP APARTMENT!
The place is VERY cozy, like for real! When me and my friends accomodated there, we didn't really want to leave it (take it as a warning!). Everything was very clean. There's alot of space - even for 5 people. Fräulein suprisingly provided us stuff for a breakfast, which was extremly nice! We had great communication, she's a fast-response type of person willing to help with anything that might trouble you. Definitely a perfect place and awesome host - recommended if you want to feel like a Berlin's citizen for a day (or more) :)
