I had a great stay in Maria Cecilia's apartment! First of all, she was super responsive, helpful, and accomodating. The apartment is great, it's basically a hotel room with a mini-fridge and microwave, which is all I needed. And it was so nice to have cleaning service every day, fresh towels, etc. The location is good. It's several blocks from the beach, which was fine for me, but maybe not ideal for those wanting to be extremely close to the beach. Just FYI to tall people: the bed is good for someone up to maybe 5'10" or 5'11", but if you are over 6', your feet will hang over the end.
Overall, I had a great stay here, and a great experience with Maria Cecilia. Yes, I absolutely would rent from her again.
Obrigado, Maria Cecilia!
