I booked a private room with a shared bathroom for 14 days. On the first night unfortunately (and this had never happened before) the door system crashed and it was impossible for me to get in. Selina staff handled it perfectly, very courteously, and did everything they could to fix this. They gave me a luxurious room for the night, while taking care of the problem, which they handled first thing in the morning, and out of respect and care for their clients, they upgraded me to a private spacious room w/ private bathroom with a view on Copacabana + a free drink.
On top of this, the hotel is very clean, the staff is very nice, the view is amazing, and the general vibe/ambiance is really pleasant. I will definitely be back. :)
