We had a brilliant stay in Martina's apartment. We were travelling with a 15 month old and Martina had a travel cot and high chair set up for us when we arrived. I knew this was a busy part Berlin so I was worried that the apartment might be loud and difficult for the baby to sleep, but that's not the case - it's a lovely quiet apartment in a great location. The bedrooms (and beds!] are very big and comfortable and the living area was perfect for us to relax in at night once the baby was asleep. There are loads of great food options nearby. I hope we can stay here again if we visit Berlin again
