One of our very nice staffs, Martin found a fabulous cafe near here. It's Coffee Pauly Roasters. It only takes 3 minutes on foot from Leo guesthouse. It would be perfect to relax drinking good coffee when you are exhausted after browsing city.
Martin suggests you to enjoy sun in terrace seats because street next to cafe is full of sunshine during the day. (I'd like to try when it's not that cold. I don't want to be snowman.)
By the way, you can trust Martin's taste because he's a French!
