The experience was great. I spent 4 nights at the apartment and enjoyed it thoroughly. The ocean view is much better than I expected from the pictures and made the stay extra special. The room is clean, has a big screen TV with many channels, location is perfect right on the corner steps away from the beach and on the same street as the metro. Ipanema is also walking distance away. Doorman is nice and there 24/7. No negatives, really except it felt a bit unusual not to have a kitchen sink and having to wash cups in the bathroom but this is what you expect from the studio and for me it totally served its purpose.
David was very professional, responsive and helpful. Offered a late checkout for 40$ extra.
