I would 100% recommend staying at their place. They are very close to public transportation to any parts of the city ( 1 min walk outside their door, 5 min to main underground, 5 min across the river to get to trains to city center). It was very quite at night which I appreciated. I was able to get to city center when I wanted and when I was done with the noise, I was able to come back and relax in their place.
One of my anxieties with traveling is finding where I am staying. Airbnb's can sometimes be a challenge since it is someone's living space and not a big hotel. Her place was easy to find and the fact she included pictures on where it was located made me feel at ease.
If you like the ability to get to city center and all the sights and then a quite place at night, you can't beat this place.
