Quest Serviced Residences are actually part of the Quest Hotel. These larger apartments are just on floors 19-25. When I was initially looking at locations, it appeared these were separately located properties.
The rooms are very spacious and include amenities such as a kitchen, separate dining room table, bedrooms, and 2 baths (at least the one we stayed in). Location is adjacent to Ayala Mall. Check in is in the Business Area which is just around the corner from the main desk.
