Carla's apartment is gorgeous and very centrally located and we had an amazing time there! First, Carla was very accommodating in allowing us to check-in early. She met us at the apartment and walked us through all of the details (including a few minor issues that we needed to know about). The apartment itself is beautiful and very spacious with very high ceilings and wood floors. There were only 3 of us staying there, but 6 people could have been comfortable in this large apartment.
The location is right at the center of Lisbon. We were a short walking distance from Time Out Market, Pink Street, and Praca de Comercio. In addition, we had everything you could think of nearby. Supermarket, coffee shops, restaurants, etc.
I highly recommend this apartment if you are planning a trip to Lisbon.
