Carolina's house is in a great location within easy access of Santa Apolonia metro station. We had no problem reaching it from the airport by metro. The excellent value €6.40 viva viagem card gave us unlimited access to metro, trams & buses for 24hours which included the trip from the airport.
The apartment itself is on the 1st floor of a beautiful old building in the heart of Alfama. It was spotlessly clean & had all the necessities for our stay. The lovely front window opens on to a small balcony.
There is a small bakery next door & a mini market just up the street. The street also contains lots of choices of bars, restaurants & gift shops.
Rui gave us great tips regarding places to eat, scenic view points & markets.
Overall I would highly recommend Carolina's apartment.
