Host was pleasantly communicative on Whatsapp and SMS. He made sure to be present upon arrival. Coming and going was easy. The original towels were small and he replaced them with nicer ones. There is no A/C which is fine for certain times of year, but it does get hot with the windows closed. With them open, you hear tons of noise from the street and area below (which is a courtyard kind of area where people gather all night long). Bathroom is quite small, and shower leaks no matter what you do, but not a big deal to hang towels over the balcony for drying. It's Paris. So these things are a part of living in a tightly packed city.
