Konstantinos is very helpful, kind and welcoming. I was reaching by plane and I appreciated his flexibility for my arrival time as well as for my departure.
You will find everything you need for a comfortable stay in this very luminous apartment. The kitchen and bathroom are well equipped and there is an elevator so carrying your suitcases is not a hassle.
The neighborhood is everything you can hope for in terms of transport (metro, buses and taxis), restaurants, food stores (supermarkets and a daily fresh market 2 minutes away, not forgetting the night store just next to the entrance of the building that stays open until late into the night). Montmartre is litterally 10-15 minutes away with the Montmartrobus that will drop you off right next to the Sacre Coeur.
I warmly recommend staying here!
