The apartment was perfect for our short stay in Lisbon. It is very small, but for the amount of time we spent in it, we did not need bigger. The location is great - Alfama is a great neighborhood and there are a lot of nice restaurants just around the corner. Rosaria was super quick to respond to any messages and each day she sent us some tips on things to do around the city.
A couple of lows though (minor points really) - the pillows were very uncomfortable and the upstairs neighbors were very loud (sounded like they were moving furniture at 1am).
Would definitely stay here again!
