The apartment is very nice and the view over Gran vía is spectacular! Also the two terraces are perfect to relax in the afternoon and early evenings. The room was ok, the door is a little bit tricky to lock.
Keep in mind that the apartment has 7 rooms and if fully booked it has a hostel-like vibe. The walls are rather thin so I could hear every word in the kitchen and if there are a lot of people, it will get loud. One time some of the guests smoked inside the apartment. I texted Ramona and she told the other guests that it was not allowed so it did not happen again.
If you want to use the washing machine you have to pay 5€ but everyone was very nice!
I would recommend the apartment for the views, the location, the terraces and the communication, but be aware that there are 6 more rooms with several beds.
