We really liked our stay in Vitalik's place. We didn't have any problem with public transport, it was easy to reach the city center from our apartment, it took about 20mins. We enjoyed our time there, even though there was a repair work on the other floor, because of the sound we couldn't sleep longer than 8am (that's the time when repair works start), but it wasn't a big problem. I would definitely recommend to stay in this place if you're searching an apartment in Riga, you won't regret!:)
