We had a very good Time in Lisbonne at Paula and zita's.
The appartment is very Nice and well located, next to tram 28.
Paula and Zita arranged a crib for our baby so we didn't have to take extra luggage, and they answered all our questions.
The only thing - but we Knew it before getting there - is that there are a lot of bars so the street is noisy during the night. But if you close the Windows, it's much Better.
