The stay with Kristina was great, we had a very good time, very cozy studio, very good location and maximum comfort with public transport and in Berlin they are really efficient ..we are sorry not to have met her in person but she was ready to fulfill every need ..only a small flaw was the mattress a little too soft but this is subjective, otherwise everything is perfect ... if we go back to Berlin I would go back to Kristina for the excellent value for money ... thanks !!
