This was a great apartment! Clean, comfortable and within walking distance to great restaurants, shops and public transport. Sofia was so helpful and gave us lots of tips and recommendations. Barrio Alto is an area area full of bars and restaurants, so if you want somewhere quiet, then this isn't the place for you. Having said that, I slept fine as the windows are double glazed and there is air conditioning. All in all we had a great 4 days in Lisbon and Sofia's apartment was perfect for us.
