Ana is an excellent host and met us for check-in. It was a simple process and we didn't see her again, but she was always very responsive on Whatsapp for all needs.
The flat location is excellent in Martim Moniz plaza (hospital exit, go straight and up the stairs to the right) and very close walk to great restaurants, tarts and some supermarkets.
The flat itself is secure and safe. There's some narrow steep steps to climb up to the 1st floor. Several towels were provided upon request including for beach use (with many thanks) and the flat stayed very cool (there is no fan or a/c) on a 35C day.
Wifi works although the speed can be a bit variable.
The kitchen has utensils and pots and a coffee maker. However it did lack any kind of basics such as oil, salt, sugar, or even coffee to use with the machine, so you'll have to get it yourself from the supermarket to make full use of the kitchen.
Overall I would happily stay here again.
