The room is beautiful and was very clean! The house is on a walk to the city centre and there is a metro station (Anjos) near. Very well located to visit the City.
The negative things (not very bad) are that the kitchen was dirty (but we didn't use it very much) because is a shared house, but the bathroom was more or less clean. The pillows for us were uncomfortable (low, hard and lumpy) and we had problems to sleep with them, but that depends on everyone's taste.
In conclusion, a good place to stay a few days and enjoy Lisbon :) Recommended.
