I highly recommend this lovely apartment in Pigalle! I spent 2 weeks here in December and felt right at home. It is in a great location close to many wonderful restaurants, the lively rue des Martyrs (which has fabulous bakeries and food shops) and convenient to the Pigalle metro station. The apartment feels very secure and quiet since it is accessed through several locked doors and a courtyard separates the building from the main street. It is nice to have a loft type room which has a small living, kitchenette and toilet on the 1st floor and large bed, huge shower and sink on the 2nd floor. The bed was very comfortable and a housekeeper came a few times to change towels and do a light cleaning.
Gaspard was a great host and very responsive to my needs. The key system is a little tricky so make sure to have your phone with you if you leave the apartment in order to get back in - I did lock myself out because the doors shut automatically and I wanted to grab something from the hallway. Luckily I had on my Apple watch and I was able to text Gaspard and he could open to door remotely - whew! Also, the apartment is on the 2nd floor and there is no elevator, very typical but just an FYI in case you have a huge bag like I did!
I had hoped to stay a few extra days but he was all booked. I will definitely look forward to staying here again on my next trip to Paris!
