I went to Lisboa with a group of 7 girls. We stayed in Vania's place and had a great time. The appartment was great, enough space and within walking distance of a lot of things in Lisboa. We did almost everything by feet.
Vania helped us very good with tips when we arrived and kept our luggage safe at the day of arrival and the day of our departure. Only thing with 7 girls is that the last two had to shower with cold water because there was not enough hot water for 7 girls :-).
If we ever went back to Lisboa, we would stay in Vania's place again, for sure!
