Location is great: walking distance to old city centre with shops, bars, restaurants, metro and train all nearby. A supermarket and bakery very close by.
The apartment is very bright, views to the city. Kitchen we only used for breakfast and had all you need.
Bathroom is rather small, some wear and tear, but good enough for the 3 of us.
No noise in the night.
Acces to the apartment is with a staircase down the main road. From the city centre there is an escalator going up in a nearby street, so after a long day in Lisbon this is useful! Be prepared to do lots of stairs in Lisbon!
Carlos is a warm host, with that typical southern flair! Responds very fast. There is a booklet with restaurant recommendations.
The only thing I need to mention is that at the moment there is a construction site just down the apartment. By 8u30 am there is a lot of noice during weekdays. So if you plan to sleep in or relax during the day, this is disturbing.
