We had a great time in Prague, which was even improved thanks to the Royal Apartments:) We had a bit of luck at first, because, due to the technical reasons, instead of getting normal room we were given the spacious apartment. So the place looked even better than in the pictures;)
We had some minor issues on the first day (i.e. lack of electricity in bedroom, no soap in one of the disposers) which were swiftly resolved by staff. We received even champaign from the staff for these little inconvieniences :)
Apart from issues mentioned above we could not say a single bad word. The place was great: always clean, spacious, well arranged, well equipped, with brand new things. Always someone on the reception eager to help you (fluently speaking English and Russian, or maybe even in some other language;). You can leave your baggage before check-in or after check-out,which was not a standard in places we stayed before. About 10-15 min walk to the Old Town, what can you want more?
We totally recommend this place, and when we will visit Prague again we will definetely stay here :)
