We had an amazing experience in Diamond Penthouse ! The apartment was very well cleaned, calm and full equiped. The view at night is so lovely.
Ira explained us very well the check in and all the information we needed for the stay.
I just recommande to take a taxi if you would like to came with big suitcase because the metro station is not so accessible with luggage (but without to go to the center it is not a problem !)
Highly recommended !
