2 of us stayed at this flat towards the end of March and had a really great stay.
We were a little confused by the numbers (jumped from 10 to 24!) so called Gonçalo who was very polite and gave clear instructions on how to find the apartment.
Antonio was there to greet us and talked us through everything to do with the flat and some pointers for the local area.
The apartment was spotlessly clean and had everything you would need plus a couple of extras (coffee machine!), which was a really nice touch.
The patio was a nice place to sit in the afternoon after a long morning's walk. Too bad the weather was a tad patchy, otherwise we would've used it a little more. Yes, there is some noise from the air con unit, however this was not an issue for us during our periods on the patio. You could not hear it at night.
On our street we had some amazing shops and everything was walkable from our location. Time Out market is around a 10min walk; An amazing nata place, Manteigaria, on the street; And the main station, Rossio, is a 10min walk away taking you to Sintra.
It was a really great apartment and we can't wait to go back and visit Lisbon again!
