Sheraton Lima Hotel
This concrete monolith may be removed from the city's best dining and nightlife options, but it offers easy access to the historic district and is just a short Metropolitano ride from San Isidro, Miraflores, or Barranco. The perfectly serviceable rooms have subdued colors, nice bathrooms, and giant windows with urban views. Popular with business travelers and tour groups, the hotel also has a convention center, a small gym, and a pool that's open from December to May.
