We didn't meet Rosa, but she and Norma were both very friendly. The apartment is well-located; there is a large supermarket a few seconds walk from the building. Easy to walk around Triana and the main historical sites (note: 30+ min walk to the Macarena area). The apartment is comfortable for 1-2 people and had everything we needed for a short visit (note: bed is two singles pushed together). Concierge and luggage storage were great. Overall very convenient!
