My friend and I arrived at two different times and Christophe met my friend first and politely greeted her.
The apartment is as per description, very nice and comfy in an amazing location, close to one of the main roads. However, it was not fully ready when my friend arrived even if we communicated the time in advance but it became available shortly after.
Communication with Christophe was smooth and easy, also when we left the apartment.
Highly recommended for your stay in Lisbon!
