Had an absolutely brilliant time staying in Fritz's top floor apartment, he was very accommodating to our group and the key exchanges were relaxed and tailored to our travel times.
The large, roomy living area had great natural light was perfect for relaxing in, and the fully equipped kitchen made cooking meals easy and fun.
The balcony was great for the smokers in the group and for having a morning cup of tea in the sun.
We comfortably slept 5 in the bedroom and felt our stay was great value for money. Worth noting that the shower had great water pressure which can be rare on holiday!
Location wise you have a small supermarket less than a minute away (Netto) and a larger, better stocked one about 5 min away (Lidl). The S-bahn Sonnenallee is also only about a mintue away.
Would highly recommend!
