My partner and I had an absolutely wonderful stay at Alex's apartment. The apartment was very neat, modern, and spacious compared to any other accommodation I've used in Paris.
Alex was extremely welcoming. Check in and out was very easy, and he met us at the time we stated we would arrive, and talked us through what we might need to know about everything within the apartment.
It was situated in an excellent location, close to the metro and within walking distance to many great areas.
As this apartment is a smoking apartment the smell of stale smoke is present at times, and after 2 days our clothes had taken on this smell. Even for my partner who is an occasional smoker it became quite intense at times. This is the only thing I would warn non-smokers about.
I would definitely stay at Alex's apartment again, and look forward to potentially coming back in the summer! Thanks very much Alex
