Great place to stay in the heart of Lisbon.
Location.
Flat is located in 10 minute walk from Praca de Commercia, near Rossio metro and ending stop of many tram and bus routes, coming across the whole city, so it's really big advantage when you want to get somewhere fastly. Also, within 2 minutes walk downstairs there's net supermarket called "Continente" ( also placed on the way to center and transports ), where you can buy all necessary supplies at modest price.
House filling.
Apartment contains all essential housing goods - coffee machine, fridge, electring cooking surface, boiler, shower, TV, wifi. But there are some disadvantages - wifi is quite slow, as whole mobile internet in Lisbon, and there no laundry washing machine, which might become an inconvenience in case you've taken not enough clothes.
Sleeping bed is average, will be suitable for most people.
So I would recommend this apartments for kind of a travellers, who don't pay much attention to details and looking for a place to sleep, a shelter above head and have a rest in a city center, for a reasonable price, without additional options.
