Stayed in the Mostecka Annex Apartment which is just a minutes walk from the hotel in a lovely old building, right near Charles Bridge. It was absolutely amazing - the pictures do not do it justice. Huge space, beautiful building, spotlessly clean, fully equipped and serviced daily. Breakfast at the hotel was a nice addition to the apartment. Staff exceptionally friendly and welcoming. Location is right next to Charles Bridge, near tram stops, easy walking into both Old Town and Castle. 100% recommend. We would stay again.
