I appreciated a lot my room which was spacious enough, nice and comfortable (it was a little noisy late in the evening because of some drunk people passing through the street, but it always stopped max around midnight). All the shared parts are cleaned many times a day (kitchen & bathrooms/toilets); actually it was quite impressive to see how fast a bathroom was cleaned right after having been used by a customer. There is a very functional and well equipped kitchen so it is easy to cook if you are tired of restaurants or just want to save your money.
The location is really really great! 2 min by walk to reach the Alfama area, and no more on the other side to get into Baixa area where are all the trendy shops, bars and restaurants. 5 min from the train station where you can take the train to Sintra or from the Aerobus' stop to go to the airport. Very convenient!
