Pros: The apartment is great, baby friendly especially that Lijie can provide a baby crib and that the Tetuan metro station is a 1 minute away and it has an elevator.
Cons: What I didn't like the most is that we rented the apt for 10 days, so it was one big amount of money, and when we asked Lijie if we can keep the luggage somewhere for a couple of hours, or if we can have a late check in, I expected that she would offer it free of charge ( since you know, we stayed for 10 days), but instead, she wanted 2 euros per bag or 10 euros for each extra hour. That I didn't like.
