I stayed in Margarida's apartment for four weeks in May and it was a great base for exploring the city, the centre of which is just down the steps really. Margarida was a very helpful and communicative host, and arranged weekly cleaning and towel/linen changes. The apartment was almost exactly as shown in the photos, and well equipped, for shorter stays especially. I was working remotely part of the time I was in Lisbon, and once I'd sorted an ethernet connection out, I managed to join video calls without problem, and used my computer as a router for my phone to connect to which provided a good wifi connection. The area the apartment is in is vibrant and diverse, with some good local spots nearby which Margarida provided tips on. I had a friend come to stay for a few nights I was there, and payed a nightly supplement to get some extra bedding and towels to use for the sofa bed.
There was from time to time a rather unpleasant smell coming up the drains, which I think is just unavoidable due to the infrastructure of the area and the age of the city. Keeping the bathroom door closed to limit it, and using bleach every few days, was my solution to this.
The apartment has a good view across the city, and the windows open wide to let the breeze in – though the alleyway beneath can be quite noisy late into the evening (the windows block out all the noise however, and the use of the fan meant I was never too hot to sleep).
All in all I had a very good stay and would happily return!
