We stayed here for 3 weeks, and ultimately, this flat was a comfortable place to stay at. It has a GREAT location (sunsets were really pretty from the balcony!), with tons of really good bakeries and restaurants. The flat itself has a comfortable bed (though a tad too too small for two big guys!), and I took a bunch of naps on the couch.
However, there are a couple of things that, unfortunately, I have to criticize.
The whole flat needs a good cleaning beyond just wiping down surfaces: curtains, AC vents, closets, floors, cutlery, drawers, microwave, toaster oven, washing machine. The listing says this flat is "new", but I very much recommend some work to help it get better.
Additionally, the listing says the flat has two bathrooms. It should be updated however to say the 2nd bathroom is located on the terrace, so you'd have to go outside on the balcony, climb the outside stairs, and there's the 2nd bathroom. This bathroom is NOT easily accessible in the middle of the night (we were here in May when it's also cold!). So, for normal purposes, the flat has a single bathroom.
Again, I want to emphasize that I like the flat in the end, it's very comfortable, but it needs some TLC.
