Carlota is the most proactive, meticulous, helpful, and professional host I've ever worked with. Being a good host myself, I'm overly critical of others, but I can only learn from Carlota.
My mother and I stayed at Carlota's Graca property for our last 3 nights in Lisboa, and had a great experience. The apartment is very well located, in the heart of Graca, at the top of one of Lisboa's many hills. It's just above the Alfama, right next to Castelo, right next to Mouraria, right next to the flea market, 28 tram stop, and an easy trip to Baixa, Chiado, and Bairro Alto.
The apartment is very well appointed, has great views from all rooms, and is very bright and comfortable. The new roll-down shutters on the bedroom and living room windows allowed us to sleep in, and blocked out the city noises. The artwork and photography around the apartment are cool and beds are comfortable (more so than others). Amenities and fixtures are new, but still true to original mid-century design.
We'd recommend this apartment to anyone, and are glad we got a chance to meet Carlota and chat with her a bit. I'd welcome her in my home anytime!
