Nina's flat is very easy to reach from Tegel Airport, and is close to public transport. The house was big enough for 4. She is also very responsive to messages. But we had a major problem of smell, we were first told it was because the previous guests smoked inside and it was iared but didnt go away. We stayed for 6 days, aired the house, it didnt go away but only got worst. After some point it wasnt smelling like smoke but something heavier. Actually we all got sick because of the smell and airing the house in that cold. The smell was also on the sheets and pillows and it didnt felt that clean and comfy at all. We reported the problem to both cleaner and Nina. She was polite and explanatory but we were told different things which was confusing and unpleasant on our side. The cleaning lady first said she had only 2 hours to air the house and then told 4 guys stayed for 4 months and smoked heavily inside and they aired for a week or so but smell didnt go, while Nina told another thing. If they happen to solve this problem, which kind of ruined our stay, house is nice. Neighbourhood is not the greatest but without problems; not very central but easy to reach by public transport.
