Zuzana's place is definitely the best choice in Prague. The apartment is great, clean and safe. More than that, there is an underground just five minutes walk from the apartment and it's also close to all the attractions.
Although we did not met Zuzana, she always replied the messages very quickly and being friendly. She would send a guide book to you before your travel which includes many useful information.
To in sum, when choosing the place to stay, don't miss this apartment! Highly recommend:)
