Let's start with the positive: the appartement really has the best location and view! The bed is big and comfortable and Patrick gave us a sheet with some really useful information (e.g. best place to change money, etc.) and even though he was a bit rushed, he was very nice.
The appartement is really pretty but has it's downsides. The shower "door" can't be fully closed. Also the stairwell is in an awful condition.
But the biggest disappointment was their "personal driver" Otto, which turned out to be a local student, who forgot to call Patrick and Thomas. That left us waiting confused infront of a closed door with no information. After she got her 28€! (There is also a big mistake on our part for not checking the distance beforehand and trusting people to make a fair price) for a 15min drive she just left. Maybe I have high standards, but in her position I would have waited until the host arrived (or at least more than a minute). I will not come here again but I still recommend the appartement for a short stay in Prague. But order a taxi before considering their driver!
