Curitiba is such a marvelous and peaceful city, easy to get around (if you have a map with directions, otherwise is chaotic).
Deville is a great quality hotel, but the Express does not reach their best. It's quite a simple hotel, similar to Ibis (prefered by most tourists). It does not include breakfast and I found it expensive (BRL8), as there is a coffee shop nearby. The traditional Deville, at 24hrs street, has higher quality.
Express is just across street of Guara Theater, one of the main theaters of the city.
But that's all, DExpress is close to Guaira and Passeio Público, nothing else. There is a market nearby for groceries.
