We were a group of four scientists staying here for a conference. It was an ideal base for us in terms of location- close to shops, restaurants, the metro, the beach. It was very clean and comfortable, with good amenities. The are is a very nice laid back part of the city that can be a welcome break from the busy centre, but is still close enough to get around easily. Sandra was very helpful and responsive to messages; we never met her in person.
The AC was only in the main living space for the apartment, not the bedrooms, meaning that at night (in August), the bedrooms would get fairly warm. Besides this it was a pleasant stay.
