One of the best Airbnb's I've stayed in. Very quiet, comfortable, well equipped and spacious. Also good for self catering - though there's no teapot or microwave.
It's set well back from the street (Valdemara Iela) so virtually no noise and a good choice of buses if you don't want to walk into town c.15 mins. Good supermarket 10 mins away (Rimi). I bought an unlimited 5 day travel pass (there's a machine at the airport) and for €15.00 thought it was good value - buses,trams,minibuses and trolleybuses. But the Riga transport system is not intuitive - worth downloading bud and tram routes. 22 or 322 brings you in from the airport but you'll have to change before Abrenes Iela. In the dark and late at night a taxi might have been a better bet (€15-20)
Overall though, a great base for exploring Riga - and you could easily walk most of it.
