A lot of people seem to not notice that Olga said she has two cats. We noticed, but my girlfriend (who has a cat for 3 years already) was still unprepared for her allergies. That wasn't Olga's fault, but people time and again miss the point that cats live here.
Olga and her children are quiet talkative. You won't get too much privacy, but if you're plan to be out of the apartment all day, this shouldn't be a problem. The room, and place in general, is really clean, although sometimes the cats can be messy in the bathroom. Comfortable bed.
Olga and her children are happy to help you in almost anyway. On my way to the airport, she even walked me to the bus stop I needed. On my last night together, they not only fed me dinner, but they invited me to help them make it too. Her sons also speak English really well. You should be able to have whole conversations without any problems.
The biggest problem I had personally was that this family likes to drink. That might be a problem for you too. However, I never felt like the drinking was a danger to me, nor did Olga and her sons ever stop treating me nicely.
I feel like I made nice friends here too. And, after a mishap with a cat and a window in one of the doors, Olga even gave me a professional haircut for free. I would still probably think about staying here if I'm ever in Riga again.
The languages spoken in this household are Russian, English, Latvian, and Bulgarian. I'd easily recommend staying here if you're traveling alone and if for a short time.
