Céline's flat is lovely, cosy and very welcoming. Its location is perfect, the subway is very close (with other stations on different lines within walking distance), and there are numerous patisseries within a few minutes walk from the flat. There is also a supermarket directly outside the flat.
We really loved our stay. The flat is well resourced and had everything we needed and more, including a smart TV, coffee pod machine and smart speakers.
The smart tech is not without issue however, and this is why we can't give it 5 stars. The listing says there is a lockbox available but this is not the case. There is instead a Nuki Smart lock.
On two occasions we could not gain access to the flat when we returned late at night. Despite preserving battery on my phone to ensure we could get in, the lock refused us entry. The first night, it was after 2am so Céline understandably did not answer the phone. This resulted in us having to stay in a local hotel for the night until Céline answered the phone the next day and opened the flat remotely. This was obviously very stressful and we were anxious about staying in a random hotel with no access to the rest of our things. This happened again the following night, but thankfully Céline was awake this time and answered the phone to us and allowed us access to the flat.
These tech issues, which were likely not Céline's fault, may not occur again, but it's important to be aware that if staying in the flat with someone else, only one of you will have access to the flat and if your phone dies you cannot get in. Thankfully neither of us needed access for medication, and thankfully the hotel on the street had rooms available otherwise this could've been much worse.
Had these issues not occurred, Céline's flat would have been perfect and we'd recommend it completely.
