Sandra's place is nice, clean, quiet and overall a very safe feeling as it is within unversity zone. Her toilets are always very clean and its looks.newly renovated too.
It's great for those attending conference at the congress center (10min walking) and also to the belem tower (15min walking). Of course there are trams and buses within few minutes walk. To Rossio is just 30min by a bus right in front.
The room itself is huge and well equiped and adequate for two person. Pretty luxiorious for me as a single traveller. Bed was comfortable. There were some nights which I could not get hot water for shower, which Sandra did explain it might be due to other housemates using up the hot water. Moat of the mornings, hot water wasnt a problem.
Sandra is quick to respond to your queries, be it food or places to visit. Sandra made sure to check on me once in a while to make sure I was doing fine.
Overall, a recommended host and place to stay in Lisbon!
