Let me start off by saying we are very picky :) Just to get it out of the way. This place will be great for most people and most likely you should just book it as the view out the window is breathtaking. The Eiffel Tower is literally in your backyard! Amazing. It is good if you are purely a tourist and just want to stay here for a few days and not really spend much time here. It's perfect for just sleeping here.
However, if you are planning a longer stay or need to cook, this is not the place for you. For one, there is NO OVEN in the kitchen, it's not a problem for most but for us it was an issue as we cook for our toddler daughter. Plus it lacked basic kitchen amenities such as wine glasses, cutlery, very basic pots, etc. For all it won't be an issue but it was important to us as we don't cook things with a microwave.
The place also lacked warmth as it just like they treat is purely for AirBnb purposes and just went on an Ikea spree. So this place lacks serious character other then this being an amazing location and the flat overall is great. It has SOOO much potential but it was missed. I would still recommend to stay here if you want to be really close to the Eiffel Tower and wave it bye before you go to sleep! :)
