Marion was a great host and made sure we had all the information we needed. The flat itself is really well located, just outside the centre but still only a short metro ride to everything and in a lively neighbourhood that's nice to spend an evening in. The flat is cosy - perfect for two or three at a stretch and has all the basics.
The only small thing was the noise from the metro in the evenings. Most people will be fine - my partner slept perfectly, but for very light sleepers like me it might be a be a problem.
