We stayed in Juan's apartment for 5 nights and really loved it. It's a cozy little place and feels really authentic. The apartment had everything that we needed. It is located in the heart of Alfama which is a warren of little streets which are full of character. There are plenty of places to eat and drink on your doorstep. Finding your way around can be difficult at first but you quickly get the hang of it. Be prepared for a few inclines on your way home as the area is built on the side of a hill so appropriate footwear is a must. There is no air-conditioning in the apartment but we got on okay as it was still quite cool in the evening.
