We had a great stay at Nena apartments! The room was spacious, well organized, clean and tidy with a nicely equipped kitchenette (nothing fancy but the essentials were there), and comfortable beds! The building managers are extremely nice and accommodating, and helped us with any question or issue that we had.
The apartment gets quite warm during the summer season, and you need to open the windows fully and turn on the fan in order to have some cool air flow. We slept with windows open (and kept quiet) at night so it was fine.
Please note that the apartment is quite public – facing a courtyard and even has a narrow window in the bathroom as well – keep that in mind if you need more privacy.
