Helpful, friendly, very quick answers, Martin is a good host. The apartment is in a great central location. The bus station and the center of Prague are within easy walking distance. Price performance is top.
Cons: I only use airbnb on my laptop, not on my mobile phone. The communication was then not optimal despite the timely provision of email and mobile phone number.
I also like to have personal contact with the host.
Prefering non-personal contact and using the airbnb app, i would totally recommend Martin and the flat.
