Excellent small apartment in the heart of Mouraria neighborhood. Very clean and perfect for a couple or small family if you don't plan to make big lunch or dinners (it's a small appartment with a small table). Being very small it is well equiped with a small dishwasher and a washing machine (always very handy when one needs them). I didn't see heating or air conditioning, but I didn't pay much attention because we didn't need either of them.
You can go walking to all the old town areas or take the Metro or the tram at Martim Moniz, 2min away. Besides being centric it was pretty quiet at night, even with the window a bit open.
The location is not very good if you plan to travel by car, because this area has some pedestrian small streets and the parking is restricted. Unless you decide to use the parking garage in Martim Moniz. But with public transport or walking is perfect. And you are not in the middle of all the tourists, although being very near to the touristic places. For instance, you can walk to the castle in 5 min. and in 10 min. you find yourself walking in Alfama streets or in Chiado (depending which direction you go).
Miguel and Carla were very nice and friendly and they are people you can talk to without problem.
Worth recommending.
