We stayed in this apartment for 6 nights.
Pros: It is spacious & well appointed with tasteful furnitures and a fairly well equipped kitchen. The apartment is very clean with wonderful soft towels. It is conveniently located: 5 min. walk from the Anjos metro station. A nice surprise: The Apt comes with a mobile phone that you can make national and international calls. Alexandra was very nice & allowed us to check-in 2 hours early.
Cons: The apartment could greatly benefit from air-conditioning. We were there at the end of September which had record heat for Lisbon (90 degrees Farenheit all 6 days). The apartment gets unbearably hot after 10:30 AM. Luckily, we are not in the apartment most of the day and when we come back around 6:30 PM or 7:30 PM, the temperature has thankfully cool down enough outside for us to open all the windows and doors to cool down the apartment. The fan was also an absolute necessity to keep us sleeping more comfortably through the nights. I would not recommend this apartment for summer rental unless air conditioning is installed. The street facing the bedroom window was also quite noisy: people talking, dogs barking, cars driving by, and a garbage truck that comes nightly between 1 AM to 2 AM in the morning makes it hard to sleep with the windows open in the main bedroom. We used the smaller bed in the living room to remedy this problem which was fine if you only have 2 people in your party.
In summary, this is a very nice apartment and a good value for your money if you come during cooler weather and don't mind riding a very short distance on the metro to get to the center of the city. However, in hot weather, be ready to deal with a baking hot apartment if you plan to stay in your room past 10:30 AM.
