Paradise Laundry at 500 Cirby Way ste b, Roseville, California.

For the most part the machines are plentiful, the laundromat is cleaned regularly. The laundromat has television with close captions and satellite channels, and music to keep you going.
Additionally they have camera monitoring to keep an eye on the place. Paradise also offers WiFi (free) and a place to charge your phone's.

Paradise is unique in that it is a green laundromat, there are 4 sizes of washers approximately 14 to 15 total and 2 sizes of dryers. I've never really counted but it's about equal to the washers. There is plenty of room to fold clothes.

If you want to do laundry after midnight bring your cell, as you will need the code to the door. This is a 24 hour laundromat. You will also need to call for the code to use the restroom facilities all 24 hours of the day, this helps to ensure that only clients use this facility, and it is kept very clean.

The parking situation can be a bit dicey, and it would be in your best interest to take care after dark, unfortunately with 7/11 around the corner this seems to be a popular area for the local homeless to gather, especially after dark. There is always asking for spare change.

As for the condition of the exterior sidewalks and parking it is all dirty, grimy, and a place where people like to clean out their cars.
All in all, keeping with daylight times and if you can avoid weekend days, getting a machine is never usually an issue.

Another plus is if you do laundry earlier in the day, Suzies Cafe is right next door and a great place for breakfast or a quick lunchtime burger, they aren't open for dinner.
