We stayed for 3 nights in this great apartment. Communication with Thomas, and his friends daisy and Leo were very smooth any easy-- no issues at all.
We were 2 couples staying, and there was enough room for everyone and the beds were comfortable. There were ample pillows and sheets to use.
The place has an amazing terrace which we spent a lot of time on. It was great to relax after sightseeing, with beautiful views of the sacre coeur. We didn't cook while there, but the kitchen was great, with lots of little basics available (all utensils, pots and pans, some oils and spices,etc).
You must go up to the sacre coeur at night ... We went and saw some amazing impromptu musicians on the steps, and explored the neighborhood behind the church .... It was perfect
I highly recommend staying here--- absolutely no issues at all!
