I was welcome by Andre's neighbour who was kind to offer a seat while waiting for Andre. In any case he arrived in 5 minutes. He spent an hour presenting the apartment and suggesting things to be seen in the city and the sorrounding.
The apartment has a perfect position in Alfama, it is well-lighted thanks to the 5 windows + the roof one, as in the photos posted on the website. Also, there is enough space for two people, as we were.
As written the apartment is on the 3rd floor. It's important to know that the stairs are not easy (both inside the apartment and outside to reach the 3rd floor). Of course Andre can't do anything for the building stairs: it is an old building as the most part in the area and this is part of its charm.
The heating system also was not the best. Fortunately, Lisbon has a wonderful climate, therefore it was not a problem during the sunny daytime. But because of windows' draught it can be a problem when evening comes. No problem during night time: bed linen and cover provided by Andre are enough to keep you warm.
Lastly, Andre is available to come or write/call you if necessary.
