All in all a great experience.
Rute picked us up from the airport which was really nice, she gave us a couple of recommendations of places that are really close to the apartment.
The apartment was perfect for a couple, it might be a bit small for three people. The kitchen/living space was compact but beautiful and perfect for breakfast or relaxing for a couple of hours before heading out for the night. The bathroom contained a shower, the bed was comfortable. The espresso machine in the kitchen is a nice touch. The wifi worked great. There is a TV but we didn't use it.
The apartment is located in Alfama which is narrow residential street and hilly. It is full of character and charm and you just stumble across amazing views. It is only a short walk to central Lisbon (20 minutes) or 5-10 minutes to the different public transport.
Would stay again without hesitation.
