Absolutely PERFECT ! I totally recommend this appartment, perfectly located in Alfama, near Santa Apolonia train station, near the center and the main places to visit. In Alfama you can listen fado everywhere, and find nice restaurants.
The appartment is very clean and cute, the beds are comfortable and it is very well equiped. Exactly like the pictures :)
Rui and his wife are very friendly and welcoming, and they gave us very good tips (places to visit in Lisbon, transports, restaurants, etc.).
Thank you both for your kindness, and for allowing us to spend a wonderful holiday in Lisbon !
