Great location - so convenient if you want to tram around Prague (which we did everyday - so cheap, efficient and local).
Loved the apartment, it was a great base for exploring the city. It was very clean and well equipped so that we could have food at the flat if we didn't want to eat out everyday. The reception staff were also incredibly helpful and friendly.
We travelled with 2 young children who also loved the stay. Comfortable beds and very helpful having the extra bedrooms. The only thing we had a slight issue with which might be relevant for other family travellers was the blinds were not quite fark enough so the children stayed up a little later than normal, but other than that we were thrilled to stay here and would recommend to family and friends.
