I had a really great time in Riga and a perfect flat thanks to Kristina. The flat is in the middle of the city centre and you can just walk around and never need the bus or any public transportation if you just want to get to know the old town of Riga. Kristina is a really nice host and the communication was very good. The only problem I had was that I didnt know how exactly I can get from the airport to the flat but you can take the bus number 22 until the station "11. novembra krastmala" and from there its a very easy 10 minutes walk.
