Paula and Alex are very helpful people and they know how to prepare you for a true Parisian experience. Paula was nice enough to provide my friend with the medicine he needed so he didn't have to see a doctor in the end.
The flat is situated in a very lively area close to some hidden attractions with not so many tourists. Well connected 24 h as well.
The only downside was that we were given one key only and we were 2 guests. So we had to either return to the flat together or plan ahead so that the one who arrives the latest holds the key. Alex wakes up very early so it's not ok to wake him up by ringing the doorbell at late hours.
But other than that it's a good place.
