The apartment is stunning, no question. It really feels luxurious, exactly like the photos. Like a well-serviced apartment in a nice hotel. Location is right on the main avenue - you're very close to lots of big hotels, and a 10-15 min walk from lovely cafes to have breakfast, dinner etc.
The building is a residential apartment complex, with a 24h doorman (no english!) so you have to wear a paper wristband the whole time as a guest, and show it when you enter. You have to book the pool (amazing!!) and gym in advance, and can only stay for 50 minutes at a time. We went every day and it was always available and we hardly even saw anyone else.
Overall, would totally recommend for a fuss-free, safe and super comfortable trip.
