Maria's accommodation is ideally situated in the middle of Lisbon, and at a good price. It's quite close to a metro station, the tram runs just down the road, and it's within walking distance of many places to eat and drink out. The flat was a reasonable size, very clean and tidy, but had an odd layout—the bedroom was in the middle, so had only a small window that could be opened for ventilation onto the hallway. I found that this made the bedroom quite humid overnight if the door was closed (i.e. if you're two people staying in the flat separately). The floors were quite thin, so noise (and sometimes smells) would percolate through. Maria was very helpful, and provides a 'guide' of sorts with information about the flat, the local area and Lisbon itself: great! Even warned us about local strikes which impacted our travel. Thanks Maria!
