I rented Juris' flat for a month in December. The flat is located very conveniently in the center of Riga within close walking distance to grocery stores, restaurants, a movie theater, pubs and the train station.
The street noise on the side of the flat that has street frontage is a bit loud all night long. If you're sensitive to that this might not be the place for you. I used the back bedroom so that was not a problem at all during my stay.
I enjoyed the spaciousness and the overall layout of the flat. There's quite a bit of room in there. If you're traveling with a larger party and looking for a place to accommodate everybody, this could be good for that. The kitchen was also very comfortable and spacious, which is not always common in Latvia so that was nice.
