We enjoyed our stay at Pierre's place. It was in a good location and super convenient to the Metro.
Our only issue was the shower drain not working the first night we got there. After traveling and having a long day we both wanted to shower but could not because the clogged drain began to flood the bathroom. I immediately messaged Pierre and the concierge, because we didn't want to damage anything by showering, and we did not get a response until we sent follow up messages the next afternoon. This was pretty inconvenient since we had to go over a day without a shower.
However, once we did get a response, Pierre sent a plumber within the next few hours and the issue was resolved.
