About
Ac Hotel Diagonal L'Illa By Marriott
AC Hotel Diagonal L'Illa By Marriott sits on Barcelona's grand Avinguda Diagonal, surrounded by gardens and parks.

The hotel keeps things simple and efficient: a 24-hour reception, express check-in/out, and a range of room types from standard queens to family rooms.

Worth weighing
4 to weigh- Slightly outside the historic centre — The hotel is positioned on Avinguda Diagonal, a bit away from the Gothic Quarter, so you'll need to take a bus or tram to reach the main tourist areas.
- No on-site parking listed — There is no parking information provided, so guests arriving by car may need to arrange parking separately.
- Street noise on the avenue side — Some rooms face Avinguda Diagonal, and guests advise choosing an inner courtyard view to avoid traffic noise.
- Pets not allowed — The hotel does not permit pets, which may be a limitation for travellers with animals.
