I think this is a good and quiet place to stay. Location is great: there are supermarket and a tram station are near the house (in two minutes walk away) and also metro station is not far off(10 minutes).
Apartment was very comfortable, clean and close to the city center. Great communication with host(Helena was very welcoming and helped us with some information about transport and made our staying as comfortable as possible) We had a great time in Prague :)
We really recommend this flat!
