The location is absolutely great (just a few steps from Lisbon Cathedral, close to Fado restaurants and Praça do Comércio), however there is currently (September 2016) huge renovation of the building in front of Avelino's apartment (hammers and drills from 7AM) and of the square behind the building (constantly 'beeping' trucks). Construction site should not however be a problem for travellers who just want to have great location for sleeping (as nights were quiet).
The apartment itself was perfectly clean. It was equipped with all of stuff to stay there for a couple of days (including washing machine and dishwasher). Two bedrooms, two separate bathrooms and two air-conditioning panels were perfect for two couples.
Avelino helped us with bags, finding parking lot (just a stroll from the apartment) and recommended us nice and cheap restaurant for locals. Absolutely worth every money that we spent. Well deserved 5/5.
