The apartment is what you see in the pictures: spacious, luminous and well equipped. It is also and super well located. It is near 2 different metro lines and also tens of bus lines. It is also close of 3 important avenues, so you'll always find good options for coffee, supermarkets, restaurants, shops and everything you need. On the other hand, as the apartment is on a 10th floor, is calm and not-noisy at all.
However, I'd like to suggest to the owners a few things to make the experience even better: include a shower curtain, a mirror in the bathroom, sheets and covers for the bed (which I think it should be included in this kind of services). Also, it would be nice to have a few chairs and a little table for the terrace, which is not equipped (beside the barbecue)
In conclusion, I stayed here for more than three weeks and I think you'll find it very comfortable for your staying.
