The apartment is really well located, around 10 minutes by foot from the clock tower (city centre) and 2-3 minutes from the dancing house. It founds itself in the middle of the old town, in a pretty street with local bars and restaurants. Nevertheless, in the night the neighborhood is really quiet, so don't worry about the noise.
Inside the apartment you will find a well-furnished, perfectly clean flat; with everything you need for your stay, from a coffee machine and dishwasher tablets to duvets and towels.
The hosts are really kind and incredibly fast in answering all your questions even when in Prague. The check-in is super easy, just make sure to organize a transfer from the Ruterra office and the apartment, since they're pretty far away especially if you're carrying a heavy luggage.
I spent a week in this flat for a friend holiday and it was simply amazing: I recommend it for anyone who's wanting to experience Prague at its fullest in the comfort of a safe and strategically positioned flat.
