Trondheim has been a great attraction for a long time: it is interesting for both lovers of active sightseeing and those, who love it slow, including travellers with kids. This is why hotels in Trondheim are really well developed and keep getting better.
Apart from luxury hotels, some of which are famous for their rich history, Trondheim has to offer more affordable hotels and hostels, and those are sometimes not less nice, due to modern interiors, freshly done renovations and distance from noisy locations. Although, it is challenge now to find a hotel in Trondheim with no Wi-Fi connection or clean towels.
The hotel prices in Trondheim are defined by several parameters. First, this is living conditions: you may want to choose a presidential suite or an eight-bed room in a hostel. Second, it's the location: the closer the hotel is to the city centre, the more expensive the room is. Third, it's the season. Summer is usually the high season for travellers and Trondheim is no exception. Good hotels in Trondheim run out of cheap rooms very quickly, which is why if you need an affordable room, you need to take care of it in advance.
