Nice and beautifull historic Hotel -it offers, if wanted, B&B- in Roskilde Center, right in the pedestrian area.
Never the less, there is the offer of free parking place in the back side of the Hotel, breakfast you book separat, if you wish.
For Dinner, you may try the restaurant in the Groundfloor, it's top, but not part of the hotel
I've been at Zleep Hotel Roskilde now a few times, every time different rooms and always top frindly staff, to me without any complains!
The best way to drive to is not via adress "Algade", that's on the front side, no cars allowed there.
Just follow from any direktion the signs to "Vikingskibsmuseet" and at the cicular traffic near the gasoline station take "Fredriksborgvej" strait ahead into "Sankt Ols Gade" over the trafficlight and direct left into the parking place.
Take the chance to see the points of interest in and around the town, not to speak from the metropolarea of Copenhagen town, Roskilde is the old capital, before Copenhagen.
Nice people, the Dom, museums, and depending of time of the year an weather festivals, a changing lovely landscape and, last but not least, the fjord -you've got me ;-) from land and the the sea as well.
Enjoy
