For an hotel in Londrina, the Cedro is great. I admit I haven't been to other hotels in the city so I'm no expert. But I'm sure that if you don't expect to be near anything in particular, can use taxis or have a car, the Cedro will be a great choice. The personnel was respectful and patient, bearing in mind that my portuguese skills are barely enough. It was not cheap, but it wasn't expensive either. The breakfast was varied and rich, the best I've seen in Brazil. Wifi worked great and it was the cleanest hotel I have been to, and I've been to many. I would surely return.
