The hosts were very accommodating and have immediately agreed to a flexible schedule depending on availability. We've received all the necessary info prior to our departure and communication was smooth.
The flat looks very much like in the photos shown, and the four of us travelling found it was comfortable; the spacious open area looking over the main street is a great space for lounging on the sofa and armchairs, and it gets beautiful natural light from the high windows.
Although central, it does not get very noisy at night, as the rooms look over an adjacent quieter street.
This is probably 5-7 minutes away from Baixa Chiado metro stop.
