Our stay was perfect, this is how renting with AirBnb should be like! The apartment is perfect for two people and equipped with everything you need for a pleasant home-feel - from toothpicks and shampoos to fast internet and variety of TV channels. Carlos was easy to communicate with and very helpful - he welcomed us with advices and some fruit and wine. The place was very clean and details were well thought of. Location is great, very authentic and very close to Rossio metro and train station (convenient for organising a day trip to Sintra for example). Both Alfama and Bairro Alto are within 15min walk. Be aware that Lisbon has a lot of hills and the apartment is located quite high - there are around 6-7 flight of stairs to it. So if you are not in a good shape it can be quite tiring.
