Petra was a good host, helped us out in the beginning with info about public transport to the city centre etc. This is a really lovely apartment with everything you need for a stay in Prague! Only caveat was that we weren't warned about how stiff the door key to the flat inside the building is, caused a bit of stress as we thought we were locked out and didn't want to break the key! Does require a lot of force to make the door unlock but we eventually got used to it.
Very conveniently located 5 minute walk from the metro station going straight to the main city centre, and the station is next door to a huge supermarket as well. Would definitely recommend this apartment for a reasonably priced place to stay which is very easy to get to from the airport and to the city!
