We stayed in the "Comfy" version of the rooms available, which is an open plan kitchen and living space, and a bedroom with an un-suite bathroom, very spacious.
The link sent when making the booking explain everything step-by-step, from check-in to check-out.
There is no staff on site, but they are available over messaging or email, they respond quickly and are super helpful and accommodating.
The apartment itself was clean, warm, well decorated, and it being an aparthotel, had everything available for a comfortable stay. It is about a 15 to 20 minute walk from the historical centre, and near an underground station and a train station with direct links to the airport, so incredibly well located.
Overall had a wonderful experience over the 3 nights I spent there, would recommend, and would gladly be back :)
