First of all, the location of apartment is perfect:supermarkets,boulangeries,restaurants are located close to it. There are 5 minutes to reach the Saint Germain and a mentro station.
Apartment are fully equipped for comforatble living, cooking etc. Its also very clean.
There is one disanvantage-too noisy neighbourhood bar and restaurant in the opposite and next building.Really hard to sleep, even with the closed windows.
Keep in mind, if you have problems with heart, or under the age of 60, guess it will be the complicated deal to reach the aprtment on foot due to 3th floor and bluffy stairs. But itsn`t count as disanvantage.
And remember to call Linda(assistant of Michel) or Michel when you are in Paris or near the apartment. Linda will meet you and let you in.
Both of them are friendly and attentive to your wishes. Just dont hesistate to ask!
