Would stay again. Large and practical flat. Its fairly priced so bargain hunters won't get much joy out of it.
Positives : view of the famous "elevator", central to shops and restaurants. I enjoyed this visit as a 3 person family and would be equally happy to use it if visiting for business with two colleagues. I don't think you would feel too claustrophobic if using it for three couples. Within 200 metres of the door you have plenty of decent restaurants and boulangeries, though the flat enabled us to cook up a complex meal if you just want to stay in. "Continente" seems to be the best supermarket within 500m.
Negatives : light switch system took some getting used to. Luggage scuff marks in one of the rooms. Dining room chairs should be replaced.
