Ericeira is absolutely lovely and we really enjoyed our stay. Magnus gave us some really good tips for local restaurants. Furthermore, the accommodation was well equipped, including the kitchen, which ensured a comfortable stay.
Unfortunately, the flat itself is clearly just the ground floor of the rest of the house and you can hear everything upstairs (in our case kids being very noisy) very well because the levels are not properly closed off/ separated by an insulated wall. Furthermore the flat could do with a bit of maintenance and a better ventilation system in the bathroom.
