We stayed at Manuel´s Place for 3 nights.
The place is perfect for excursions around the city, because it’s very centrally located. The sights are well reachable by foot as its only 10 min walk away from the Praça do Comércio, aswell as the castle in the other direction.

We did have a minor struggle finding the way to the apartment when we first arrived in Lisboa- so unless you are travelling with a gps you should still risk a closer look at google maps to get an idea where to go!!.
Even the gps we had with us didn’t quite find this tiny street. So what you are looking for is the street called Largo Terreirinho, than take the tiny footpath uphill between No 27 and 28.
Once you´ve found it, it´s not much trouble at all to get along.

The apartment is new and very well equipped and decorated. Manuel is a great host and very helpful. as a welcome gift he prepared pasteis de nata - custard cups, originally from a pastry shop in Belem and a typical dish in Protugal.
We would always stay there again and recommend it to everyone thinking about a nice little cozy but clean place, for spending a good time in Lisboa.

another tip for you to get to know the City is doing a free city tour. payment based on tips you give to the guides afterwards: http://www.discoverwalks.com/lisbon-walking-tours/alfama-walking-tour-lisbon/
