The apartment was as great as the pictures suggest with the location being exceptional to see local tourist spots. Magnus was very responsive and was present at check in even though it was late at night. There was all the amenities in the flat that you could want and this helps to eases the need to pack a lot of small items (toiletries etc).
Only negative comment which is not a reflection of Magnus or the apartment was the neighbours were doing some building work at the time of the visit (sept 2nd -6th) which meant there was a lot of construction noise from 7.30am.
I would strongly recommend the apartment to anyone visiting Prague.
