Cute one-room apartment, perfect for couples, all basic things (towels, toilet paper, hair drier, soap, shower supplies etc.) were provided, even some basics for breakfast (toast, butter, marmelade, coffee, apples). The place looked exactly as shown in the pictures. The bed was comfortable, hot water worked well.
The neighbourhood was not too loud (relatively quiet actully for Madrid), but still it is very centrally located, many sights within walking distance and the metro is really close as well. We would stay here again.
