We spent 8 nights at this flat in September 2022 and overall had a good experience. We appreciated Mariam's prompt responses to messages as well as her willingness to adjust our check-out process so we could get to the airport quite early in the morning. The flat was aesthetically pleasing, very clean, and in an excellent location. It's actually across the street from a collège (middle school). A small nice surprise was that a diffuser was included with the hair dryer. As others have observed, the full-size sofa bed was quite comfortable!
One recommendation we have for other guests is to purchase toilet paper at the store when you pick up the keys. The listing states that toilet paper is included but 1 roll was provided for our week-long stay. We needed to buy more the morning after our arrival. The same is true for the coffee pods (if you use them, which we did not – I believe 3 were provided). If you intend to use the washing machine, you'll also need to purchase detergent.
There's very little activity on the street where the flat is located (apart from the occasional noise from the students at school). You will hear guests in other flats, though, both through the walls and through the open windows/small courtyard below. When people aren't home, it's extremely quiet. We share this just in case you are extra sensitive to noise – using noise-cancelling headphones helped a lot. :)
It took us a couple days to get the hang of how to unlock and lock the flat door, but we managed! And as others have said, the stairs are narrow and uneven and the stairwell is quite dark – this is to be expected in an older building and it wasn't a problem for us at all. Please take your time going up/down the stairs. Don't try to carry all your luggage at once!
We would recommend this flat to travelers who appreciate simplicity and comfort!
