I recommend Chez Tuga to 100%. First of all: the place and room was nice, clean and had a lot of atmosphere, the building is art-deco and the corridor of the flat is decorated for example with beautiful portuguese azulejos (tiles) - and not to forget the big roofgarden (nice view)!! of course where one can sit with some people and have a good time. The owner Domingoas is a great person who creates a good atmosphere with her patent, friendly and charismatic personality. Last but not least: the area is great, near to the centre, Alfama and all the other places one may visit during a stay in Lisbon. So, thumbs up to Chez Tuga.
