·The Hotel Portixol,a hotel that oozes(渗透) style and has thoughtful extras in Palma Majorca.

·Location

In the bay of Portixol,a 30-minute walk or 10-minute cycle east of the old town,overlooking Portixol port.

·Character

The square white building,with its blue shutters(百叶窗) and dark wooden balconies,stands out as you approach Portixol. Inside as well as out,Hotel Portixol oozes style - wicker(柳条) sofas in a shade deck. Thoughtful extras include free bicycle hire and telescopes in each room.

·Rooms

Thirteen of the 26 rooms have balconies,overlooking the sea. All have large showers and king-size beds. Our corner room had double glass doors on two sides which created a much-needed breeze.

·Food

Breakfast is a feast,with a huge selection of fresh fruit,yogurts,cereals,meats,cheeses and breads. The lunch and dinner menus mix traditional Mediterranean food with eastern and European classics.

·Why Palma?

Parts of Majorca have a certain reputation,but calm,sweet Palma is a far shout from the island's busy and sometimes tacky(俗气的) beach resorts so popular with hen and buck parties.

The Majorcan capital is also one of the easiest short-break destinations in Europe. The old town is a 10-minute taxi ride from Palma airport,while the tangled(乱蓬蓬的)streets inside the old city wall combine the best restaurants,shopping and culture Majorca has to offer.

While very hot in summer,temperatures remain pleasant during the rest of the year.

·Getting there

Easy Jet flies to Palma from most airports in the UK,from £29.99 one way. A taxi from Palma airport to the city centre costs about £8; or you can catch a bus which costs a few euros.
