We had a really good stay here. The apartment is in a great location in Alfama, in the heart of the old town and within walking distance to everything. We went pretty much everywhere by foot which is the best way to explore the city. It's a a very cool space, much bigger than it looks in the pictures, decorated with care, and Carlos is a kind and helpful host with loads of recommendations who went out of his way to make us feel welcome.
A couple of small downsides that were out of Carlos's control: unfortuntately there is a big building site directly next to the house and the work on this woke us up a few times. There's also some noise from across the street until late but we're deep sleepers so that was fine. Slightly more intrusive was the smell/atmosphere of damp in the apartment. On a couple of days we came back to find our sheets very slightly damp because of the moisture in the air.
Those things aside we had a really wonderful trip. Thank you Carlos!
