Everything was perfect for us when it came to conveniency of transport, budget and comfort. Alesia metro station was only 5 minutes walk from the apartment, and the main attractions in Paris were only 30 minutes on the metro.
Stephane was very helpful and I would recommend his apartment when in Paris.
The only negative I can say is the 5 flight of stairs when travelling with a baby 😂 but that's our downside. I'm sure this won't be the case for most.
