I'm so sorry for these problems.
Aix en Provence old town is being restauring since 2 years. Some days are more noisy than others. I always notice the workers because I don't want my guests are surprised. In the building, yes, it's old and needed to be restauring also but we wait for the end of the workers in the district and we'll repare it. In summer, in the south of France , in the old towns there's roaches and rats..... We always organised strong treatments against and unfortunately when they dye they all come out. A cleaning society is supposed to clean the stairs every week, but they didn't do it last week and I didn't know the problem.
I was in a foreign country with a jet lag. In that case, my friend Virginie is supposed to welcome my guests and help them in needed. You had her phone number. I received your message late in the night for me and I thought in was not a emergency. Of course I would have answered to you sooner if it was.
Well, I hope you will keep a good record of your stay and I do appologize for you feelings.
