Our stay at Maik's apartment delivered what we expected from our low budget stay! The location was good (if you're willing to move around by public transport), and even though it says that it's a "Small but nice apartment", it wasn't that small! The kitchen though was quite small, so I would recommend that you don't plan to prepare very big meals. Also, if you're very sensitive to the smell of tobacco, this might not be the right place for you to stay, BUT at the same time, we stayed at several airbnbs in Germany, and all of them had a slight smell of tobacco since you're apparently allowed to smoke inside at several places in Germany, so that seemes to be a common "problem". You could also hear a bit of noise from the outside, so if you're very, very sensitive to noise, just be prepared for it.
A tip, if you like Vietnamese food, I would 100 percent recommend Viet Bowl just a few minutes walk away from the apartment!
And finally, if you're looking for what you see in the pictures, you can totally trust your host Maik and book the not so small and nice apartment! This accommodation suited five interrailing girls very well!
