Excellent location close to public transport and walkable distance from main sights. Great restaurants, shops in very easy walking distance - some on same street as Antonio's place. Antonio was very easy to communicate with and check-in/check-out was very flexible. Antonio was even proactive in offering a later check out because nobody was moving in on the day we left - this gave us a bit more breathing room which was very welcome. The flat suited our group of 4 perfectly. The flat is huge. Very quiet even though it is so central. Much bigger than we expected which was a real bonus and we found the decor charming. One thing to know is that one bedroom is considerably bigger than the other with 2 double beds in it. Our plan had been for 2 friends to share in each of the bedrooms, but we ended up with a group of 3 in one room and 1 person in the smaller room. Perfect for us. Thank you Antonio. We'd love to stay again next time we are in Berlin.
