Jose's apartment in the Bairro Alto was a really good base from which to explore Lisbon. Nightlife around the apartment is thriving throughout the week, and there are lots of good restaurants along the small cobbled streets. It is close to the centre of the city, and within walking distance of the river (though the walk uphill to get back is a bit of a challenge).
The apartment itself is well equipped and quite spacious, with separate rooms for kitchen, bathroom, bedroom and living room. The wifi connection was extremely fast, and Jose was very helpful when we were trying to set it up (we ended up having to use the WPA key written on the modem, rather than the S/N code provided). The kitchen was fairly spacious and contained all necessary appliances, but the gas stove needs a proper oven lighter - currently it is easy to burn yourself with the small lighter provided. Hot water in the shower was a bit unreliable - on the first two days the gas water heater failed to trigger, but later in our stay the problem fixed itself.
Despite some minor problems, Jose's apartment was perfectly livable and located in the heart of Lisbon - we would recommend it.
