My family (my husband and I and my parents) stayed in Charles' beautiful apartment and had a wonderful stay. The apartment has clearly been newly renovated, the bathroom and kitchen are brand new (kitchen is fully equipped, everything we needed), and we loved the style - there are three separate bedrooms and each one has its own great "personality'! It was great to have space as well, the apartment would be perfect for bigger families or groups of friends.
Charles was a great host, responded quickly to all our questions and gave heaps of tips for exploring Lisbon and the neighbourhood. He also arranged a taxi for us from the airport for a cheap flat rate, which was really convenient and meant we didn't have to worry about finding our way (especially with our limited Portugese!).
The apartment couldn't be more central, minutes walk from the historical centre of Baxia Chiado, with beautiful old-fashioned cafes, upmarket stores, lovely family-run restaurants, museums, etc. The street was so typical and quaint, we learnt the name, Travessa da Laranjeira, means "alley of the orange trees" because of the trees planted down the centre. The Bica (a typical Portuguese funicular) runs up from the main street down to the river and is just in the next street, a ride on it is a must!!
There is also a great look out that is a short stroll from the apartment where we loved to sit and have a drink overlooking the river.
All in all, a great experience. We loved the apartment, and the city, and look forward to coming back next time with friends.
