This is a great apartment for up to 4 people in the very popular (justifiably) St Germain Des Pres district with multiple cafes and restaurants nearby. Within 100 metres of both St Germain Des Pres and Mabillon Metro stations, there is easy access to everywhere in Paris.
The apartment itself is compact and bijou. I went with my two teenage sons (15 and 17), and, whilst we didn’t spend too much time in the apartment, I don’t think there would have been much space if we’d had a fourth person. There are two en-suite bathrooms, with good quality showers in both.
Communication with Rosa was very good.
All in all, we’d definitely return.
