We had a great time at Joao's apartment. The apartment is situated next to São Jorge Castle in the beautiful Alfama district. It's a bit of a climb up the hills of Lisbon to reach but it's worth the effort! The views of the River Tagus are lovely and occasionally you may be woken up by the local peacocks - I presume these are from the castle and were a bizarre sight the first time we saw it! I would highly recommend this apartment if you choose to stay in Lisbon.
