Great location and fully functional place. Eduarda is extremely responsive and fast to take action in case anything is needed/doesn't work as planned.
Have been staying in the apartment for over 2 months- it is very well located, close to anything you might need and max 10-15 min walk from great restaurants, parks, groceries, etc. The apartment has a working washing machine and dishwasher, it is very well ventilated and the air conditioning - also well functioning - is located in the bedroom.
The building is rather old so you do hear the upstairs neighbors walking a lot: I had to sleep with ear plugs every night. Also, the street and neighboring buildings are having some constructions done every now and then, so it can be a bit noisy if you work from home during the week (sometimes on Saturdays as well).
Overall, I had a very smooth stay in Lisbon, it was great to have a safe place to come back to from all the traveling I did, and Eduarda was the perfect host!
