Went just before lockdown. Stayed at Hotel Kampa, and also stayed at Kampa Garden. In the old town but a few minutes from Charles Bridge.
Thoroughly recommend both hotels. Evening shots of the city, tram trails and night time of the old town heading up to the castle suggested. Spend daylight wandering around the city, with as little gear as possible. Dusk/dark is best. Early mornings on Charles Bridge too, but I am NOT a morning person
