Yusss, using a laundromat is how I imagined my character would solve the laundry problem when it's too cold, haha! Also, YES to Google Street View. Absolute life saver, especially when it comes to drawing comic panels.
As for setting the comic in a different country... yeah, it IS a bit daunting, but I just love doing research, so it's also fun and I love the fact that I get to learn a lot of things tbh, I think setting my comic in my own country would also be daunting, unless I set it in my own town. While I might be more familiar with the laws and general culture, there are A LOT of things that can wildly vary, even from one town to another (accents, surnames & most common names, nightlife, public transport, typical food, family gatherings, traditions... heck, even freaking dinner time can be completely different from North to South :'D). And, from what I managed to learn, I think the same applies to a lot of other countries, too. Soooo... no matter which location you choose, research is always key
