We chose Pierre's apartment on the basis of the excellent reviews for it and for Pierre as a host. Unfortunately we found that neither the apartment nor Pierre lived up to our expectations. The apartment is extremely small, is accessible only via two flights of steep step (not mentioned in description), and is deficient in the facilities it provides in several areas - eg cooking facilities are limited (no microwave/oven), linen for kitchen and bed were inadequate (one tea towel, no tablecloth, no extra blankets), there was no ironing equipment. We did not see Pierre during our stay and received none of the greetings and helpful advice/instructions which previous guests had commented on.
On the positive side, the apartment is in a pleasant location, was clean, and may be suitable for a quick 1-2 night stay, but we would not recommend it for anything further than that.
