We loved our stay at Yanissa's apartment.
Yanissa was very helpful when we ended up coming in a bit later than we had intended and communication was easy from start to finish. The apartment was clean and plenty of space for my daughter and myself. Dug the bottle of wine waiting for us ;-)
It was great having multiple cafes to choose from right outside our door and it was particularly pleasant being able to walk to Sacre Coeur at dusk when it was less crowded and felt more intimate.
The apartment is very convenient to two metro stops and we easily made it to other parts of the city but there was plenty of exploring to do by foot in the immediate area.
For us the apartment was perfect but a few things to consider- the bathroom is very tiny (as are most in this area I imagine), the kitchen, too, is tiny and the lift is very tiny indeed. We were happy using the stairs but they would be challenging with very large luggage.
One last thing- the apartment is on the 5th floor. This enabled us to leave the windows open day and night while still feeling safe and secure. Despite all of the cafes, the street was surprisingly quiet at night and the breeze was wonderful.
All in all would definitely recommend.
