Olivier's apartment was a perfect base from which to explore Paris, being only 5 minutes walk from the Republique Metro,and was easy to find from Olivier's directions.
The neighbourhood was safe, lively (good bars, particularly the very bohemian Caravanne, one of Olivier's recommendations) and convenient, with a well-stocked and good value supermarket one minute's walk away. The canalside location was particularly attractive at night, and we spent one lovely, laid back evening sat on the banks, alongside the locals, with a bottle of wine or two, until the early hours.
Olivier himself was a very considerate and helpful host, who communicated well by text, both to arrange our initial meeting and to make sure we were ok during our stay. The bottle of wine he left for us was a lovely gesture. :o)
The flat itself is small but cosy, and had everything we needed, other than a kettle, which would have been useful (we boiled up a pan of water to make tea!). It's very secure, with key codes to get into the main building and inside door, but the corridors in the apartment block are very dark, with timed lighting, so we made sure we located the light switch as soon as we exited the lift!
Overall, we had a very good and relaxed experience at Olivier's and would definitely stay there again. :o)
