You're sent a code via SMS prior to your arrival, and this gives you 24-hour access to the building and your apartment. A concierge service is available if you do need it.
If you don't feel like cooking, you can enjoy a daily continental buffet breakfast. Other nice-to-haves include a car park and self-service laundry room.
