We paid 100 EUR each for two nights. 50 EUR/night/person is low for a hotel like that but it was too much, if you're in for 15 days.
25 EUR/day will be midclass. You can go below and above according to preferences.
Parking is no issue. There's always somwhere protected. But we left the on a street for three nights. Locked them up, and there was no issues.
