I didn't actually meet Maya, but she sent a friend to wait for us and give us the keys, and we arrived in the middle of the night. She was very kind and communication was great, she also left us a paper with some tips and a guide of the city.
The apartment is not central but the metro is close by and the view from the windows is great. Plus The interior is elegant and very clean! I totally recommend and were I to go back to Oslo I would book again here!
