Overall I had a great time in Lisbon and the apartment itself surely is ok, however I think it isn't as great as the photos and reviews show off, due to the following reasons:
* a central location in the entertainment district right in front of the main bus station may be handy but it's not exactly the most 'cozy' environment. I personally prefer the charm of the historic area but in Lisbon fortunately everything is within walking distance.
* it situated on the 6th floor, be prepared for a sporty challenge when carrying your baggage up.
* the place gives a messy impression with outdated and rather odd decoration.
* if both bedrooms are occupied by 2 adults each it might get a bit too narrow.
* although certainly with good intentions in my opinion quite chaotic communication and a very present host.
