We arrived and as per her instructions, we looked for a lock box and could not find out outside the building. I messaged her and she responded within 20 minutes, but sadly it was 20 minutes wasted because she didn't give me the information (apartment number, real location of the lock box).
The space was very clean and comfortable but the internet didn't work at all, so if you're going here and need internet.. this is not the place for you.
I don't recommend or not recommend this place, it had ups and downs but proper communication with Marina would have made our stay much more enjoyable and less stressful.
