We stayed at Alex and Caroline and it was terrific. The apt. is clean . quiet and comfy. Terrific location for everything espescially for wandering about. Shops,cafes,restaurants and trams are very close. We had no car and are glad. Parking can be a challenge in Lisbon but there is a public parking lot 2 blks. away.
Had some minor glitches with wi-fi but Caroline solved the problem promptly.
