The Multilux Hotel in Riga is very much a budget hotel, so if you expect chocolates on the bedspread or fawning attendants, this is not the place for you. Having said that, it is cheap, central, and clean. More details . . .
When I opened the door to the hotel I was a bit shocked by the stairway entry: chipped masonry, plaster-patched walls, etc., but I had seen worse in other parts of Europe so I trudged up to the second-floor reception area. The receptionist was not effusive, but she was polite and let me check into my room even though I was hours early. My room was on the sixth floor and that did mean a climb. If you are of a certain age or have mobility problems, this would not work for you. The higher I climbed the more decrepit the walls looked so I was apprehensive when I opened the room of my door. But it was fine: spare, yes, but large, clean, with big windows and a perfectly serviceable bathroom. The only concern I had was the door: it's very old wood and textured glass -- not soundproof at all. If the other people in your end of the hotel were loud this might be a problem. It wasn't for me (but then I never travel without earplugs).
Breakfast was basic but fillin. Not fancy by any means, but there were eggs, cold cuts, cheese, bread, juice, cucumbers. The standard Eastern European breakfast that I grew up with. If you need croissants, not for you, but if you just want calories, you've hit gold. And yes, the coffee was instant -- so have tea.
The area is very good: there is a supermarket on the corner, numerous restaurants within a block, and a seemingly endless number of alcohol shops a stone's throw away. You can walk to Old Town easily in 15 minutes.
The hotel has several routers for wifi.
Final note -- I asked the receptionist if there was a laundromat nearby. She told me to give my clothes to the women in the kitchen. They returned them the next day. Easy as pie.
