The location of the apartment is fantastic - the Voltaire metro stop is at the end of the street that took us wherever we needed! At the opposite end of the street we explored Rue de Charonne that had lovely spots for dinner and various pastry/bakery options.
The apartment itself is on the second floor - the stairs are spiral but we got up them with two large samsonite suitcases and no issues! Despite being close to central streets, the location was very quiet, and we loved having the windows open for fresh cool air in the morning. The beds were very comfortable (and the pillows were amazing) - the sofa bed is large and spacious, with myself (6’1) fitting easily - only a tiny bit creaky but very impressive. The apartment also has gorgeous light quality with windows - we loved looking down onto the street below and across at what we discovered was the local gym hidden inside an old market/warehouse style building.
Our last day was very warm - there is no A/C but two portable fans were provided - they worked perfectly aside from a large dust collection!
The only other two things we struggled with were the coffee machine - we got pods but water seemed to leak from the bottom with no coffee coming out which was a shame, and the washing machine leaving detergent still on the clothes. The portable small clothes line was fantastic though, with our things drying in hours thanks to the afternoon warmth and sunshine!
Overall we loved our time in Paris, and roaming the streets near the apartment and exploring Bastille was a highlight!
