Looking for the best city to visit during my reading week

Title: Discovering the Ideal European Destination for a 4–5 Day Reading Week

A university student in the UK is planning a brief European city break during a forthcoming reading week. With family scattered across the distance, the goal is to spend 4–5 days in a vibrant city before returning to London to continue studies.

The traveler has shortlisted five cities based on flight and accommodation affordability, as well as overall appeal:

• Lisbon
• Madrid
• Munich
• Rome
• Vienna

Only one city can be visited during this period, so input is welcome to help determine the best option. Key considerations include cost, safety, and the practicality of English use. While Paris was once a possibility, current timing has shifted priorities.

Additional questions include:
– How comfortable is English in each city (noting that the traveler speaks Spanish in Madrid)?
– Are there any notable safety or logistical considerations for short European city breaks in these locations?
– Suggestions for must-see attractions, day trips, or experiences in these cities, and any alternative recommendations outside this list.

If you have insights, recommendations, or itineraries that align with a short, budget-conscious, safe, and English-friendly city break, please share.
