Miguel and Clara were great hosts! When we arrived they were flexible about us arriving a bit earlier than expected. We were welcomed with wine and given ideas for our trip in Lisbon which is really lovely.
The apartment itself was very clean and at night time it was very quiet so you'll be able to have a good night's sleep. It is also cool enough in this summer's heat.
Central Lisbon is in walking distance and so are a lot of the monuments. There is also a supermarket a few minutes away from the apartment which is very handy.
