Stayed for 3 wonderful nights here, highly recommend this place.
The apartment is recently renovated, very clean, nicely decorated and has all amenities. It offers a stunning view to the Vltava river and the Charles Bridge. You can spend hours just sitting by the window and looking at this beauty. The apartment is quite big to host up to 4 people, for 2 it's just huge.
The location is perfect as well. It's very close the Old Town and other tourist attractions including the Prague Castle but at the same time it's calm and very romantic at night. There are plenty of bars and restaurants nearby so you won't stay hungry. The nearest metro station is within 5 minutes walk.
