Good location - close to underground, shops, town centre.
Contact with hosts was good and prompt.
Locals were all very nice and polite.
Lisbon is a pleasant town, lots to do, transport is excellent.
IMO:- Tram 28 overrated (glad I didn't pay extra). Beaches good (we liked Estoril) - but beware of high tide. Santa Clara Fleamarket (short uphill walk from flat) was large - good for LPs. Timeout market (food hall) is very nice, but a bit pricey. We had a good meal with a good view at "Ponto Final" - book ahead (catch the ferry from Cais do Sodre to Almada -it is then a 20 minute walk along the river towards the bridge).
