Welcome to Porvoo!
If you have time, make a day trip to Porvoo. It's definitely worth it! Especially the Old Town with old wooden houses, lovely interior shops, small lifestyle boutiques, delicatessens, cafes...
Porvoo is not a totally new nor strange place for me as I studied there for four years, ages ago though. Well, it has changed a lot for better since those times, but even then the Old Town was so idyllic. I remember Cafe Helmi from those years, but all the other lovely stores were new to me.
As I never lived in Porvoo, I took every morning for four years a bus from Helsinki to Porvoo, so it is pretty easy to visit there even if you don't have a car. It's about 50km from Helsinki.
Here are some of the pics I took of the Old Town.
The silk butterfly blouse in the last pic was so cute & soft...
ps. for lunch I suggest Bistro Sinne, even though it's not in the Old Town, but you'll find it easily.
