We enjoyed our stay at Mira's appartment. Several factors contributed to this feeling. Firstly, the host and her husband are very kind and pleasant people who are keen to satisfy and meet expectations of the guests. - Upon our arrival and checking up the appartment they asked whether we need some extra bedding pieces or something for the kitchen (additional utensils, cuttlery, for example) and even provided us with an extra unductive stove. The hosts were also very helpful in providing some practical tips regarding sightseengs, grocery shops around in the area, etc. On top of that, we were wellcomed with a bottle of sparkling wine and desserts on arrival. Secondly, even though the appartment is small it is clean and well maintained which makes you fell comfortable.
Wen it comes to place location I can say that the neighborhood is pretty safe and quiet. There is a grocery shop and a supermarked just around the corner and a reasonably priced Uzbek restaurang serving authentic food which I would strongly recommend (very convenient to have such as a back-up on your way home). Downtown is about 20 minutes walk from the site so you don't feel attached to public transportation.
If you are 2-3 people coming to Riga, I would recommend this place.
