Even though we arrived a bit early, Ricardo was already there to welcome us and had made sure that the studio was spotless. The flat is very tastefully furnished, the living room has a great view, the bedroom is sunny and the kitchen well equipped. The apartment is only minutes away from Buttes Chaumont, the best place in Paris for picknick and pétanque (Ricardo even supplies you with the boules!). And listen to Ricardo's restaurant suggestions, we chose one he recommended from one of the books he keeps in the studio, and had a splendid evening. Thanks a lot again Ricardo!
(PS: Yes, the flat has a chemical toilet which has a bit of a camping feel to it, but not to worry, and there is a 'normal' one on the corridor if you prefer..)
