The host is very friendly and communicative, she gave clear instructions and was very reliable. The place is quite small for two people but I think that is part of the Parisian lifestyle where each tiny space is valuable and must be used wisely. Packed with coffee machine and a cute terrace out front where you can enjoy the morning beverage and sunshine (we got lucky to have some). It is very close to Sacre-Coeur (just a few energizing steps upwards), Esplace Dali, and also close to shops and restaurants in Montmartre (downhill). There are four Metro stations around the area, each equidistant from the studio (6-8 minutes walking time). There is also a Carrefour and other supermarkets in the vicinity.
Great experience overall, I would recommend this place to solo travellers and/or couples.
