I strongly recommend Tromsø City Living Hotel, just right in the city centre, a step behind all main attractions and transportation. The rooms are bright, clean and comfortable, with all the amenities you can need whatever is just for a few days or several weeks. I was in different rooms for several years and all of them have they charm, the heated bathroom floors are nice in winter times with a powerful shower, the kitchen have all you need and the complimentary high speed wifi is working really good… and you have the chance to use the loundry where you can wash and dry your clothes free of charge as well! The staff is very friendly and helpful, caring about your needs, and I really mean it! Definitely I can't imagine a better place to stay in Tromsø whenever it is for bussiness or pleasure.
