We had a really great stay at Rosa de Alfama, with a real 3 star service as Rita came to pick us up at the airport on the day of our arrival.
The place is very clean, very comfy (especially the bed), perfect for a few days in Lisboa. The location is also great as a lot of the great sites are walking distance from the apartment.
For the ones that would like to listen to Fado music, there is a really great place 2 minutes away from the apartment called : Dragau de Alfama, which I would really recommend (lots of local people, the food is average but the atmosphere is really great and the prices are totally normal.. compared to a number of touristy places).
Only one little thing (but I am sure Rita will fix it soon) : the hot water basin is very small and even if we had very quick showers, the second person going to the shower did not have anymore hot water.
I definitely recommend this place !
