The flat was really stylish and location was amazing on a really pretty and trendy street with bars and cafe's etc. 3 of us stayed in the flat and it was perfect for us - sure it would be no problem with 4 people staying either. We walked to most parts of Berlin as the location was ideal - if you need the metro it was only 5 mins away. We had a Lidl nearby which was handy for what we needed, but lots of great food places nice and close too. Martina and Charlotte were easily contactable and really helpful. We had towels and a hairdryer provided in the flat...essentially it was absolutely perfect! Thanks MaCha :)
