The room is perfect for 1 person for 1-2 nights. It’s indeed quite small, as it’s said in the description, but it’s a good fit if you’re only looking for a place to sleep.
Pretty well located within 5 minutes walking from Gran Via and 2-3 minutes to the closest supermarket.
However, we would have appreciated a little more flexibility regarding our bags; we asked to leave them in the airbnb 1-2 hours before/after the check in/check out time but unfortunately this was not possible.
