Jakub is an incredibly pleasant man and an absolute pleasure to work with. His rules are fair and do not ask too much from guests
As for the apartment itself, we were shocked at how good value it was for us. It had everything required for cooking, cleaning and just relaxing, with a HD TV, kitchen and living area. That's not to mention the terrace up the stairs with one of the most amazing views of Prague Castle one could ask for. It's located half a minute from the Charles bridge and about 10 minutes to the nearby train station.
As a group of twelve, we ended up paying €20 less each than what we would have gotten for a hostel and got something that was much better than any hostel.
Amazing experience overall and highly satisfied.
