We stayed here for 3 nights during our trip to Lisbon. The apartment is located near a few landmarks so it's easy to have a taxi or Uber get you there. It's at the bottom of the hill in Alfama which we really enjoyed because once we were tired from exploring all day we knew it was downhill all the way back. There were also some great restaurants and bakeries a stone's throw away. It's located off the main street in an alley away from the noise.
Check-in was easy and the place was amazingly clean. There was air conditioning in the unit as well as cable TV with a lot of English channels. The bed was really comfortable (memory foam) and had a big couch to relax on after a long day of exploring.
We would highly recommend this place if you're looking to stay in the Alfama area.
