The apartment was totally gorgeous - looks exactly as it does in the pictures, spotlessly clean, very comfy beds, it has everything you need (though note there is no toaster - though there is a grill option on the microwave which worked for that!) and it's in a great location - only couple of minutes from tram stops and metro, you can be in central Prague in less than 10 mins and lots of fab eateries around including a wonderful farmer's market at the square up the road and a couple of fab tapas places on the same street.
Petra was an absolutely amazing host! We arrived very late in the evening but she was still there to greet us personally and give us all the information we needed including helpful maps and recommendations of where to go. Contact ahead of our arrival was brilliant and extremely prompt as well - from sending a very useful welcome pack with restaurant recommendations and then making a reservation for a special dinner for my mother's birthday - nothing was too much trouble. It was the perfect place for our stay and would highly recommend it!
