Carla's apartment is an excellent choice for visiting Lisbon. It is very well located, a 15 minutes walk to most of the major attractions. If you don't want to walk it is two minutes away from the nearest Metro station. There is plenty of good places to eat and a couple of supermarkets within two or three minutes walk.
The place was in a perfectly clean condition and the check-in was very smooth, with a combination box.
There was a problem with the hot water pressure, which was promptly dealt with. The hot water pressure is perfect now.
I would definitely recommend this apartment!
