We were there last autumn in October. The weather was nice, although you can always ask for more sun but only one person is in charge there !
The house was excellent to stay in, a bit difficult to find the first time.
We were 2 families 2 x parents, 2 x kids 18 years of age and 2 x kids 15 years of age.
The house was excellent because you had room for one family at the top floor(2 bedrooms and 1 bathroom), one family at the lower floor(3 bedrooms and 2 bathrooms) and the common room including kitchen and huge Sofa/TV area at the middle floor(1 half bathroom), this way you could stay on your own if you wanted to, but who wanted that with the excellent common room that invited for gathering.
The common room was perfect for gathering, the young people was either playing games, reading or watching TV while the adults was cooking while tasting the local wine, all kitchen facilities available.
The outside areas was perfect for sun-bathing and taking a dive in the pool(although a bit cold at this time of the year). Also nice barbecue area(but no sun after 15:00 hrs. at the time of year we were there)
The owner provided an outstanding service just to e. g. the 4 "boys" wanted to watch a second football match at Camp Nou(champions league) but could not get tickets, the owner was contacted for help and managed to get us tickets, outstanding service.
The house was equipped with central heating and this worked perfect.
The house was well maintained and clean upon arrival and we bought the after stay cleaning for a fair price, very convenient.
The location of the house was perfect for going into Barcelona(approx. 25-30 min with car or taking the train from Sitges) or going to Sitges(aprrox. 10 min with car) and the excellent beaches and even though we were there in October did the Mediterranean behave with a very nice temperature. Sitges is a very quit, nice and cozy city.
Also very good golf courses was very close to the house(one of the families are enthusiastic golf fanatics)
There are both nice restaurants in Barcelona and in the nearby city Sitges
The overall score for our experience with the houses and the surroundings was perfect but I am sure you would see the full potential of the house better in the summer period(warm pool and better use of the terraces, not so much sun in the autumn)
