Carla's place is great! My husband and I stayed for 4 nights and we really happy with the apartment. It was very clean and well equipped. Everything you need in the kitchen, towels for the bathroom, extra blankets, and a heater and dehumidifier (which we really appreciated, as nights were a bit damp - it was March). The location was perfect for us, we were able to walk basically everywhere, and its very close to THE meeting place of Lisbon (Luis Coimbes square). Perfect place to grab a coffee, situate yourself and do some people watching. Lots of great little places to eat around the apartment too, and very close to Bairro Alto.
In terms of Carla as a host, she was so nice! Vey sweet and thoughtful, she had some Portuguese sweets and chocolate for our arrival and let us check out late to accommodate our bus schedule. Also very quick to respond to email.
Defintely recommend! Thanks for everything Carla!
