The location of this place is perfect, if you want to stay within walking distance of most central Lisbon, but still away from the busiest tourist areas. Also very well connections by train and busses. If you want to cook yourself, this place has the means, a good market and a couple of decent shops nearby. Plenty of nice places to eat out, when you want to do so. Also good museums and galleries nearby.
River view is a very big plus, and the busy street is further away, so the traffic does not bother.
But if you are a tall person, you learn to be humble - lots of possibilities to bang your head!
All in all: lots of light, small but well functioning, cosy. Excelent location. What more could you want? Even exercise comes with the package (5. floor, stairs)!
Obrigada!
