Housing
Madrid is an expensive city by Spanish standards and even European standards. Buying property in Madrid is extremely expensive and even renting can be slightly pricier than expected. Expect to pay on average 300,000 euros for a 2-bedroom apartment or about 1000 euros per month to rent.
Tipping
Tipping is not mandatory in Spain, however, it is always welcomed by waiters, hairdressers and taxi drivers. If you do wish to tip a 10% tip is perfectly acceptable.
Gratuity is not usually included on restaurant bills, but some restaurants include a service charge for large groups of people (10+).
