I really enjoyed my stay in Riga! Although my host was not at home at the time I arrived (what felt uncomfortable before the trip), she did her utmost best to provide me the keys through another person located near the hostel. Everything was well explained on documents I received by mail, even with maps included.
Also I got clear instructions about transport to hostel from airport on my request.
As she knew that I'm a "light" sleeper and the hostel was not fully booked, she provided me with a double room at the back of the hostel instead of a single room at the street site. Nights were colder and so the room, so I got extra blanket and a heater.
Anna only came by in the evenings as she started studying.
But in simple words: Anna is a nice host and does a lot to make it comfortable for the guest.
The street itself is rather busy and noisy. Also kitchen equipment is very limited and not always very handy so not for people who have the intention to cook a lot themselves.
