We had a very pleasant stay at Francisco's apartment. The location is very residential and felt safe. The building is quiet so we had a great night's sleep. The apartment was spotless and has all of the basics you would require for a few days' stay. We walked into town each day but you could easily grab a bus too. It's about 10 mins walk to Santa Justa Train Station, and about 25 to 30 minutes walk to the old town, cathedral, etc. Communication was perfect and check-in. Highly recommend.
