The appartment is perfect for two people! Everything was very clean and the view from the balcony is just amazing! Even if the appartment is located in the middle of barrio alto it's not loud in the night, just the normal noises from the streets. Hand-over of the keys, check-in and -out was easy going, we just had to call and they came in time to the appartment. The appartment is in the 5th floor and the stairway is quite narrow so you shouldn't be afraid of hights or have problems with walking. But for us (two women, 27 years) it was really the perfect apartment for our fantastic stay in lisboa! I definitelly recommend this place :)
