We enjoyed our stay at Alex's studio apartment. We were met by Alexander, Alex's son and helped us with our luggage. It is on the very top floor (7th floor, although it is called 6th floor because their ground floor is 0, 2nd floor is 1 etc, etc). No elevators, but it was good for exercise.
The apartment was very Parisian. It was cute and cozy. Ideal for couples or single traveller. It was also equipped with a cute kitchen so you can cook whatever. Some spices, condiments were also provided. The washroom was compact but is typical for a Paris studio. Some toiletries were also provided. A hairdryer was available for use as well.
The location was really great! Few minutes walk to Guy Moquet metro station and No. 31 bus that takes you to Gare du Nord or Arc de Triomphe. It was close to a lot of restaurants, shops, grocery stores and pharmacy.
Alex was prompt in replying to our questions.
I recommend Alex's place if you are staying in Paris on a budget.
