My overall experience was positive. We didn't meet João in person but we were welcomed by his friend David. On the positive side the flat is very spacious and well located, wi-fi is strong and reaches all rooms. Some minor works should be done in the flat though. All dichroic lamps in the lavabo and the corridor that leads to the kitchen for example were not working, what meant anyone using the lavabo at night would need to rely on the moonlight to see anything. I also find João should make it more clear in the flat's description that it only has one full bathroom and a lavabo, instead of two bathrooms. We were 11 and given we were all following the same agenda and had to take a shower at the same time it was a bit of a challenge. Warm water from the boiler would run out after a few showers and most of us had to actually deal with cold showers. I am aware this is not only João's flat problem, but an overall central Lisbon issue. Still, my advice is that you don't take it too seriously the full capacity advertised by the flat if you need more comfort. Anyway, João was flexible enough to allow us to check in earlier. We couldn't check out later because there were other people coming, but I'm sure João would had been flexible as well to allow us a late check out or at least allow us to leave the luggages for the day if the flat were to be empty. Despite the points made here, I would still recommend this flat, just set your expectations accordingly.
