Absolutely fantastic place - highly recommended!
First of all, the location is amazing. Everything is within walking distance - Wenceslas Square and the international train station are 5 mins walk away.
The apartment itself is beautiful - everything is just as described in the pictures, and very clean and comfortable (really, much better than any hotel I’ve ever been to, and I’ve been to some great hotels).
The check-in hostess was lovely, and very helpful - she explained everything meticulously despite the late hour (our check-in was late).
Magnus was very accommodating and nice, and answered all my questions before and during our stay very quickly.
All in all, I don’t have even one complaint - just the opposite. Will definitely come back to this apartment.
