I felt very nicely welcomed by Carlos, even though he was not able to be there to greet me in person. (He sent a lovely friend to meet me and show me around). His directions from the train terminal were easy to understand, his little maps were very helpful, the flat was *perfect*!! and is reflected accurately by the photos. You can take a taxi from the airport (between 50 and 75 Euros!) but if you don't have a lot of luggage ( I had a daypack and a carry-on sized rollie), the train is only 10 Euros and it's a short walk to the flat from the station. This is a good way to get the feel of the neighborhood. Yes, the flat is four flights up to your front door, so no worries about gaining weight on the croissants! It's full of beauty and charm- spiral stairs, plants along the way. The neighborhood was fun, lively and full of artists, not very quiet at night on the street, (it's Summer in Paris, after all!) but the bedroom was in the back and very nice for sleeping. I felt safe walking around, even late in the evenings. Plenty of cross ventilation from the two big windows front and back, so the temperature was always fine. Leaning out just a bit from the bedroom window I could see the dome of Sacre Coeur- and this became a favorite touchstone, morning and evening. Shopping for food (and wine) in the neighborhood was easy and I enjoyed having a little place to fix my breakfasts and make snacks. I saved a lot of money this way, leaving funds for dinners out. Plus, I liked starting the day with fresh bread from the bakery around the corner to go with my eggs and (oh my god) the amazing french butter. Let's see...what else? Oh, plenty of hot water for the shower, a tiny but very efficient and serviceable kitchen with pots pans, dishes, etc. all there. Wifi in the apt. (a big plus for smartphone usage there in Europe). Carlos was always reachable by text or call with answers to whatever queries I could come up with. He even brought me pastries one morning! I felt like a true Parisienne, living there. I experienced Paris in a way I would not have, had I gone to a hotel. Thank you Carlos! I want to come back!
