Catarina’s place is in a perfect location - very central and easy to get everywhere. Bairro Alto is literally next door with some nice bars and restaurants (make sure to check out the Park bar which is above a car park!). Aerobus from the airport stops 10mins walk away. Note that the walk is rather steep and with the apartment on the top floor this is not recommend for those with walking problems otherwise great walk to stay fit while on holidays:-)
Catarina was always quick to respond to any questions we may have had and was always really helpful. Apartment is very spacious and has a lovely view.
