We loved our stay at Yefims apartment a lot.
The flat was clean, well furnished and had everything we needed stored in a cupboard somewhere.
The location was great, as it is very central and has bus and train station close by.
All the major tourist spots at reachable by foot and we did not regret skipping a car on this trip.
The old town of Riga is just 10min walk away and we enjoyed wandering around so much.
Would recommend a lot!
