Unfortunately I couldn't personally meet Olena. Check in was supposed to be easy, an when I had a problem, she wouldn't take my call. She said afterwards that her phone was down or something... anyway, she always replied on Air B&B chat.
The place is greatly spacious, very very clean and comfortable. You'll find a little booklet with Rīga's main attractions, and some literature on the area. Location is superb really! Right in the gorgeous and impressive Rīga's old medieval town. It's a 3 minutes walk from everywhere, and some 25 minutes by taxi from the Airport.
Check in was easy, but the entrance of the building is quite "funky". It smells humidity and there was a drunk neighbor inside the building. So, in order for him to let me in, I had to give him an euro... bad luck I believe, but inside the flat was perfect, and you don't feel the outside bad smell, so... you should be ok.
The shades don't close properly, so, expect to wake up early in the morning with some sunshine illuminating the room!
New appliances, new furniture, extremely clean and comfortable... paardoxal though.
