We had a lovely stay at the apartment, the location in Alfama was absolutely perfect to explore Lisbon from as was walking distance to most of the city and close to metro stops. The terrace was a great size and had a perfect view of the river for some early evening drinks before dinner.
A couple of points that would be worth noting if you are planning on staying here:
1) The property is on the 6th floor with no elevator, which may be difficult for some (especially after a day exploring the city). We didn't find it too much trouble but could see others might.
2) The apartment is built into the eaves of the roof, which means there are lots of parts through the flat which have very low ceiling height. We are both quite tall, so hit our heads a few times, but we got used to it by the end of the holiday. The problem areas were around the bed and in the bathroom
3) During our stay there was building work going on next door, which wasn't too noisy and was finished by 5 each day and wasn't an issue for us as we were out during the days. But could be annoying if you were planning to stay in the flat a lot.
4) A couple of items didn't work during our stay (main light in bedroom, one window didn't shut properly & cracked toilet seat), but it didn't affect our stay hugely and could be easily fixed
Overall we had a great time in Lisbon and the flat was perfect to allow us to explore the city fully. Alexandre was great and easy to reach at all times to assist where required. Thanks a lot!
