My Friend and I stayed at Cat's place for 5 nights,and we really enjoyed our time there.The apartment is perfectly located in Barrio Alto,yet still quite enough to have a good night's sleep.It is a very cosy place,nicely decorated,clean and the perfect spot to spend a couple of nights and explore Lisbon.Cat was quick to reply and very helpful with giving tips.She also allowed us to stay in the apartment a little bit longer on the day of our departure.We did not meet her in person,but her husband welcomed me and everything went very smooth.We can thoroughly recommend to stay at this apartment!
