My mother, sister and I had a great time in Lisbon. The flat was ideal for us. It is central, near the miradouro da graça, and you can buy coffee and snacks next door.
Of course, as it's central, it can be a bit noisy from time to time, but it didn't bother us.
Also, we got some good tips and Ana came around immediately, when we had some issues with the fuse and fixed it.
Totally recommend. Thank you!
