I was in Lisbon for 3 weeks. Everything was as described in the website: small room but the location is more than great and at least you can sleep well the night (the bed was really fine) while living in the center of Bairro Alto, one of the most lively neighborhoods of Lisbon. The whole flat was always clean and Gonçalo has always been very reactive when I needed some informations.
Would recommend this room for anyone coming alone in Lisbon and looking for a cheap and well located accommodation!
Have fun :)
