Our stay in Estoril was lovely!
The Hotel Palácio Estoril is absolutely wonderful. Good location, close to restaurantes and many other interesting points. The breakfast is a five star breakfast, excellent. The other facilities are very good (bar, spa, pool etc). The service is great, like an old fashioned five star hotel. Example they turn the bed down at night and leave a chocolate! The ONLY complaint I have is the bathroom (a little small). The room itself is fine with a spectacular view.
However this did not spoil our stay as everything else was excellent!
The golf courses of Estoril (Estoril Golf Club and Estoril Blue Course): maintenance, layout, service, pleasure playing, clubhouse, etc;
The golf course was lovely to play, the clubhouse is a bit "old", but we just used the course so we enjoyed our golf. Sadly on the last day it rained.
