The apartment was great for our large group with decent sized bedrooms and communal spaces. We particularly enjoyed the terrace which was put to good use. The apartment was spotlessly clean, light, airy and secure. The only thing that some may view as a negative is that the apartment is on a busy road with some traffic noise - but this didn't bother our group.
The location of the apartment is central and only a few minutes from the metro. We only used this once during our stay as we found it easier to walk around the city.
Special thanks goes to our host Pedro for whom nothing was too much trouble - from organising transfers and recommending bars, restaurants and even the best beaches to visit.
I would definitely stay in the apartment again if visiting Lisbon again in a large group.
