We really loved this place! Riga is an interesting city and even when it rained we felt very much at home ;)
The apartment has a very nice view over a Park, it is furnished with taste and you can feel very cosy. The stairs did not bother us - the building is an old building from the Soviet times - but the apartment is completely renovated and tidy, clean and beautiful.
Coming there from the train station is easy and also getting around Riga from there is good with many busses and tramways, but Walking to the city centre is also fine!
Communication with Rinalds was easy and nice!
I would 100% recommend the place!
