Location is brilliant, the apartment has a great view and very helpful hosts! There are cheaper places in Prague, but I would recommend spending a tiny bit more and having a worry-free time.
We arrived a bit late (after 22:30) which was no problem for checking in, as Daria was waiting for us in the apartment and directed us to the pre-booked parking place (two minutes walking). Late checkout was also possible. The apartment itself was very clean and warm.
We really liked the place and will definitely like to book it again next time we are in Prague.
