I stayed 8 night at Marius' place. The flat is amazing, as you can expect from the pictures. Very stylish, light and quiet,decorated with lot of details: this apartment has a soul! And the bed is very comfortable, I slept very well. The location is perfect too, you have coffee shops, restaurants, supermarket and bus lines at walking distance.
I did not meet Marius in person but it was very easy to communicate with him and he let very good tips in the flat.
This was the best airbnb experience I had so far :-) Highly recommended!
