Olga responded super fast and the place was really cool. She also reacted quickly when something was missing or not in order.
The place is well equipped with everything you need to even cook or do laundry.
It is really well located, you can hardly be in a more central spot. The windows are towards a small side alley, so it's not super crowded in front of the house. But (especially if you leave the window open in warmer months) you will hear some noise from people passing by in the night as the apartment is on the ground floor and Riga Old Town is quite touristy. So pack ear plugs if you are sensitive to noise.
We enjoyed our stay and would choose the place again next time.
