We stayed at Berna's place for a month and it's amazing. The house was easy to find, VERY clean, and had EVERYTHING, we just felt at home. Berna thought about everything to the little detail. It's close to the tramway of alibeyköy (10 min of nice walk) from which you can take the metro anywhere in Istanbul. The surrounding is quiet and it's a cozy place. The reception is helpful and the place felt safe. Berna was very helpful and responsive whenever we needed her. Highly recommended and worth every penny!
