Apartment location was excellent! We had an early arrival and they allowed us to drop our luggage off during the cleaning time which allowed us to go explore for the afternoon which we greatly appreciated. We also had to alter our stay dates which was easily accommodated by João, again making our stay much easier.
The apartment itself was perfect, we had no issues. There are a lot of stairs but we were made aware of this beforehand. We were 3 guests and the sofa bed was made and ready for us and was a comfortable sleep. Overall would grealy reccomend for your Lisbon trip!
