Yannick's flat is very pleasant; it's in a very central location with great cafes/restaurants nearby (e.g. Minimes). The flat is delightfully warm in winter. it's up 6 slights of stairs but this does provide nice views! The shower is in a low ceiling area so difficult to use if you're over 5'6 but it's above a bath.The bed/pillows seemed to be memory foam& was comfortable. it's well equipped.we arrived at an awkward time when yannick was about to travel so he'd explained in advance he wouldn't have time to clean so i can't vouch for how clean it would be but the flat wasn't in a terrible mess and he agreed to subtract the cleaning fee when asked and he was very personable and helpful in all of my dealings with him. Overall I'd recommend this place.For Eurostar travellers, It took about 25 minutes from gate du Nord via the metro - probably a bit less in a cab.
