If you value location, cleanliness, and hospitality I recommend Petrutz's apartment. He was such a great host I owe him an honest review. For starters his place is located right in the Gothic Quarter. All the great restaurants and metro transit spots are within 5 min walking. He respects your privacy and provides whatever accommodation you request. Bonus points: I went on a 2 day side trip to Paris, and he laundered and pressed my bag of dirty laundry left in the room without even me requesting it. AMAZING HOST. Book his place.
