The place itself is ok. The bathroom smelt pretty bad and, as mentioned in other reviews, is hard to wash in. The walls are very thin so noise prevented us from sleeping (construction until late and very loud people in the streets). However for the price you get to be in a great area of Alfama with easy access to the city by foot.
Also a special mention should go to Sofia who went out of her way to check us in after our flight was diverted to Faro and we were a lot later than expected. She was very welcoming and helpful despite the long day and it was very much appreciated.
