Indra would have been available for us the whole time to answer questions or give a hint about a good place in Riga. We visited some of your recommended places, the cat coffee, Meza iela, the market(s), Pumburi (funny!), Zanis Lipke, Kalnciena... Actually the apartment is for two persons but Indra gave us a sleeping pad the very first day - thank you! (Although the bed is big). We ate some times in the park and the rest of the time you can observe the fishermen or jogger or parents from the window. A calm environment. We walked almost always when we had to reach the old or new town on the other side of Daugava. Ps. Don't miss the cheap new town (Miit, Pot Stock,..) and the Laima 'Serenade' chocolate + triffle confect if you're vegan!
