Very central location, less than 10 min walk from Cais de Sodre where there are trains, metro and all kinds of public transport. It is quite a touristy area, with lots of bars, restaurants and stores only a few meters away.
The apartment is in a very narrow back street, which probably makes it quieter than most in the area, the windows look straight into another apartment across from it. Not a lot of natural light, but it's totally fine if you're going to be outside most of the time.
I would recommend the place for short-term stays. Inside it had everything you need - tv, fast internet, kitchen with most of what you need to cook a meal, laundry. The double bed was comfortable. The second bedroom has two double beds, but we never used it. Keep in mind - that room's window looks out at a wall and has zero light. Bathroom was clean. Shower cabin can get a little leaky on the sides.
Ines was very kind and responsive and would quickly sort out any issues we had.
