MP is a great host. He picked us up at the airport and drove us back too. Plus he gave us great pieces of advice to visit the city and was very reactive when we needed information. About the flat - it is cosy, clean, we had enough space and the personalized decoration is pretty cool. We just missed the light of the day but this problem is more related to the city's buildings agencement than to the flat itself.
To sum up, we had a good time :)!
