The apartment is a little bit far from the city center, in a residential neighbourhood, however Oskars gave us instructions how to use Taxify app which was really cheap and helpful to use (around 3€ per way to the city center for 4 people).
We had the pleasure of meeting Oskars in person. He is very nice, communicative and his place surprised us a lot. We had a great time in there spending some days in the beautiful city of Riga. Thank you!
