Eduardo has been very nice and extremely flexible to accomodate us. We arrived quite late in Naples and he waited for us at his appartment to give us the keys, he offered us a glass of wine and left a pocket guide in French in the appartment.
On the positive side : The appartment is clean and confortable for two. The weather was not awesome but we still very much enjoyed the very nice terasse for our breakfast and evening drinks (there is a small barbecue also!!)
Two minor comments to avoid surprises : the shower is a bit small for big guys like me but very manageable :) ; the appartment is on the sixth floor.
Otherwise extremely conveniently located in the heart of the historic center and close to a few nice restaurants and amenities (Carrefour market close by). Don't be surprised by the tags on the walls etc., Naples is not an extremely clean city!
