Katerinas apartment is located very well to get to know the city and a nice place for a weekend-long stay. It is close to public transport but in a quite street. Sadly, it rained a lot when we were visiting Prague, but the garden looked like a beautiful place to have a coffee. All in all, we felt comfortable, but the flat could have been a little cleaner.
Communication and check-in were easy even if we didn't meet Katerina in person.
