My boyfriend and I stayed at Kaspars and Indra's apartment for 8 nights.
It is located in a quiet neighbourhood. We used the Taxify app every day to get to the old town and it took us about 10-15 minutes.
The building has an elevator which was really helpful after a long day of walking.
Another big plus was the piano which was really fun to play and the speakers which we connected to my phone to listen to music.
I would highly recommend checking out Kalnciema Market which is a 5 minute walk away and is held every Saturday. The food is phenomenal and all homemade so we bought some for our stay and some to bring home.
There was also a list of shops, bakeries, restaurants in walking distance the hosts left which was really helpful.
Both the apartment and Riga were wonderful and we enjoyed our stay very much.
