The apartment really does have the most amazing view. Clean,warm,comfortable and well appointed for self catering.The stairs may prove difficult for those with mobility issues but they are as listed.
The location was great for Old Town Square and the supermarket and shopping centre are close by. We didn't use any public transport as we preferred to walk, including the Charles bridge and castle area.
Check in and check out was straightforward and the taxis were kindly arranged for us.
