Checking in and out is really easy, and there's a nice parking spot behind the building, which made arrival careless and comfortable.
The apartment is big and has all the necessary equipment. The location is good: right next to some small restaurants, a (breakfast) bakery and a 24h liquor store :P
The metro stops right outside the door, it's never a long wait and just a ~15 minute ride from the center. Tip: a 5-person ticket is just €25 and can be used for 24 hours on all modes of transport within zone AB.
The apartment itself was reasonably clean, although some things were broken upon arrival, which made it feel a bit tatty at times.
All in all, it was a pleasant stay, and I can still recommend this place.
