I just came back from staying in Vero's lovely flat. It is perfectly represented in the photos, modern but cozy and only 5 minutes from 3 Metro stations in Montmartre. The facilities were perfect, she has a great shower and I especially enjoyed the espresso machine in the morning! I did not meet Vero, but her friend Cherif was charming and showed me everything I needed to know.
Two people could be comfortable in the flat. I had it to myself and felt like there was definitely a lot of space. I recommend Vero's flat and would stay there again.
