Fantastic stay. Martina really helpful, friendly, accommodating and flexible. Apartment smart, uncluttered and comfortable on a good street with nice restaurants and relaxed feel. Good location as easy to walk to a lot of sites or could use the Metro five minutes away. Despite the restaurants it was still quiet at night - no noise - so slept well. Berlin is a great place. Will come back and will try to stay at Martina's then too. Thank you!
