We had a great stay at the apartment of Luana. It is great for groups, because it has four bedrooms, a big livingroom and two bathrooms. The place is in a busy area close to the central station and a 15 minute walk away from the old centre. Unfortunately the city was asleep when we stayed (August) so there wasn't a lot to do in the city. When you're with a group, it is good to know that the noise level can't be really high at night, because neighbours can easily experience problems because of the noise.
