Carlota was a great host, very helpful and gave great recommendations for attractions and restaurants.
The location of the apartment was perfect, steps away from the miradouro in Alfama.
The neighborhood and the apartment were small and cozy. We visited in late April, so the weather was very temperate but be aware that the apartment has no central heat or a/c.
It was easy to see all the sites in Lisbon as the tram line was right outside our doorstep.
Our only complaint is that the address is not labeled on the apartment, it was just an un-marked door, so it was a bit hard to find. We had to ask someone on the street for directions.
