Wonderful stay with Lucas and family. He was an excellent host, organised, knowledgeable and available without ever being intrusive. The apartment is a great size, clean, lovely hot shower, comfortable bed, ample kitchen, good Wi-Fi. We stayed as a couple but two more adults/children would not have been uncomfortable. It's a ground floor self contained apartment, really secure as there is a communal foyer with security door leading to a courtyard, and then another security door to Lucas's home. The area felt quiet and safe and yet the main cultural spots were readily accessible (on our first full day we walked to jardins Luxembourg and Notre Dame in 35-40 mins, and when pushed for time on 2nd, we took metro to sacre coeur and monmartre in 10-15 mins). There are two small express super markets within 250m and a lovely patisserie in the same area were we got our fresh croissants every morning.
Lucas had pre arranged dinner for our first night at prosper et fortunee (his recommendation - which was superb) and had provided maps and detailed info on public transport and local shops/restaurants etc.
Great host, great trip. Would highly recommend Lucas's apartment.
