Me, my boyfriend and our baby stayed at Petra's apartment for six nights and had a wonderful time. Petra was a great host and provided us with everything we needed. The apartment is big enough for 2 1/2 persons, was clean and tidy and has free parking possibilities just a 10-minute-walk away. The bus station is very close and the bus takes about 10-15 minutes to the city centre. Despite being situated at a heavily used main road the apartment is perfectly quite as the windows close very tightly.
We definitely recommend the apartment and Petra as host to everyone who wants to have a good time at Prague.
