We stayed in Benoit's flat for 2 nights. The place was a nice and clean. The location is so convenient that we could walk to all our destinations within 30 minutes. There are many shops and restaurants around in the 5th and 6th. As the previous guests described, the heating and hot water were all working well. The doorlady at no.6 was very helpful. She passed us the key and showed us all the switches in the flat. The only part that others not mentioning is the noise from the metro, but it was perfectly fine for short-stay travellers because we didn't stay in the flat on day time and we slept tight.
