This is a beautifully furnished tiny house right next to the Portuguese Academy of Sciences, in the old part of the city, within easy walking distance (if you take into account Lisbon's steep, cobbled streets) to most major sights in Lisbon. Ideal for one or two people, with comfortable furniture and a beautiful art collection on the walls. Miguel was a great host -- he always responded to all my messages within minutes, despite the occasional difference of several hours before our respective time zones. Moreover, my arrival was delayed due to a late international flight, and Miguel waited to let me in and show me around. The only caveat I would give to future guests is that the house's electrical system is old, so running multiple appliances at once is not always possible, but it's easy to plan when to run the heater, the boiler, or the electric kettle one at a time.
